A 950 kg truck accelerates from rest to 15 m/s in 2.3 seconds as it drives down a rough road. If the forward force of the engine is 7000 newtons, determine the force of friction between the tires and the road. 804 N 6,196 N 7,250 N 14,250 N
Answer:
804 N
Explanation:
We are given;
Mass; m = 950 kg
Initial velocity; u = 0 m/s
Final velocity; v = 15 m/s
Time; t = 2.3 s
Engine force; F_e = 7000 N
From Newton's first equation of motion;
v = u + at
15 = 0 + 2.3a
a = 15/2.3
a = 6.5217 m/s²
From Newton's second law of motion and since friction always opposes motion, we have;
F_e - F_f = ma
Where F_f is frictional force.
Thus;
F_f = F_e - ma
F_f = 7000 - (950 × 6.5217)
F_f ≈ 804 N

One least interesting thing about collisions?
A bullet is fired from a rifle with an initial velocity of 300 m/s at an angle of 25 degrees from the horizontal.
1. Calculate the horizontal and vertical components of the velocity
2. Calculate the time spent in the air
3. Calculate the maximum height
4. Calculate the horizontal distance
Answer:
1. The horizontal component of the velocity is approximately 271.89 m/s
The vertical component of the velocity is approximately 126.79 m/s
2. The time the bullet spends in the air is approximately 25.85 seconds
3. The maximum height reached by the bullet is approximately 819.35 meters
4. The horizontal distance is approximately 7028.36 meters
Explanation:
The initial velocity of the bullet = 300 m/s
The angle at which the bullet was fired, θ = 25° from the horizontal
1. The horizontal component of the velocity vₓ = The component of the velocity in the x-direction
vₓ = v × cos(θ)
Substituting gives;
vₓ = 300 × cos(25°) ≈ 271.89 m/s
The vertical component of the velocity [tex]u_y[/tex] = The component of the velocity in the y-direction
[tex]v_y[/tex] = v × sin(θ)
Substituting gives;
[tex]u_y[/tex] = 300 × sin(25°) ≈ 126.79 m/s
2. The time the bullet takes to maximum height, t = 1/2 × The time the bullet spends in the air
The following is the relevant kinematic equation for the vertical motion of the bullet;
v = u - g × t
Where;
[tex]v_y[/tex] = The final velocity vertical velocity = (0 at maximum height)
[tex]u_y[/tex] = The initial vertical velocity ≈ 126.79 m/s
g = The acceleration due to gravity = 9.81 m/s²
t = The time in flight of the bullet
Substituting gives;
0 = 126.79 - 9.81 × t
t ≈ 126.79/9.81 ≈ 12.924 s
The time the bullet spends in the air = 2 × The time the bullet takes to maximum height
∴ The time the bullet spends in the air ≈ 2 × 12.924 ≈ 25.85
The time the bullet spends in the air ≈ 25.85 seconds
3. The maximum height reached is given from the following kinematic equation;
[tex]u_y[/tex]² = 2 × g × h
Where;
h = The maximum height reached by the bullet
∴ h = [tex]u_y[/tex]²/(2 × g)
h = 126.79²/(2 × 9.81) = 819.35
The maximum height reached by the bullet = h = 819.35 meters
4. The horizontal distance travelled by the bullet = Horizontal component of the velocity of the bullet × The time the bullet spends in the air
∴ The horizontal distance travelled by the bullet = 271.89 × 25.85 ≈ 7028.36
The horizontal distance travelled by the bullet ≈ 7028.36 meters.

An object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second squared in the direction of its motion for a distance fof 5 meters. What is the final speed of the object
Answer:
6 m/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 4 m/s
Acceleration (a) = 2 m/s²
Distance (s) = 5 m
Final velocity (v) =?
The final velocity of the object can obtained as shown below:
v² = u² + 2as
v² = 4² + (2 × 2 × 5)
v² = 16 + 20
v² = 36
Take the square root of both side.
v = √36
v = 6 m/s
Therefore, the final speed of the object is 6 m/s.
The final speed of the object as it accelerates uniformly in the direction of its motion is 6m/s.
Given the data in the question;
Initial speed; [tex]u = 4.0m/s[/tex]Acceleration; [tex]a = 2.0m/s^2[/tex]Distance; [tex]s = 5m[/tex]Final speed; [tex]v = \ ?[/tex]
To determine the final speed of the object, we use the third equation of motion:
[tex]v^2 = u^2 + 2as[/tex]
Where v is the final speed or velocity, u is the initial velocity, a is the acceleration and s is the distance covered.
We substitute our given values into the equation
[tex]v^2 = [(4.0m/s)^2] + [ 2\ *\ 2.0m/s^2\ *\ 5m ]\\\\v^2 = 16m^2/s^2 + 20m^2/s^2\\\\v^2 = 36m^2/s^2\\\\v = \sqrt{36m^2/s^2} \\\\v = 6m/s[/tex]
Therefore, the final speed of the object as it accelerates uniformly in the direction of its motion is 6m/s.

a kid uses a slingshot to shoot a rock at a target. when the kid applies a net force of 8.68 N forward, the rock accelerates at a rate of 12.4 m/s^2 forward. What is the rocks mass?
Answer:
0.7kg
Explanation:
Given parameters:
Force on the rock = 8.68N
Acceleration = 12.4m/s²
Unknown:
Mass of the rock = ?
Solution:
From newton's second law of motion, the net force on a body is the product of mass and acceleration
Net force = mass x acceleration
Now insert the parameters and solve the problem;
8.68 = mass x 12.4
mass = [tex]\frac{8.68}{12.4}[/tex] = 0.7kg
A farmer is walking through a field at a velocity of +0.5 meters per second (m/s) relative to the ground. At the same time, he is throwing seeds in front of him at a velocity of +2.1 m/s relative to himself. What is the velocity of the seeds relative to the ground as they travel through the air?
Answer:
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.
Explanation:
From Physics, we know that the absolute velocity of the seeds ([tex]v_{S}[/tex]) is the sum of the absolute velocity of the farmer ([tex]v_{F}[/tex]) and the velocity of the seeds relative to the farmer ([tex]v_{S/F}[/tex]), all measured in meters per second. That is:
[tex]v_{S} = v_{F}+v_{S/F}[/tex] (1)
If we know that [tex]v_{F} = 0.5\,\frac{m}{s}[/tex] and [tex]v_{S/F} = 2.1\,\frac{m}{s}[/tex], then the velocity of the seeds relative to the ground is:
[tex]v_{S} =0.5\,\frac{m}{s} + 2.1\,\frac{m}{s}[/tex]
[tex]v_{S} = 2.6\,\frac{m}{s}[/tex]
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.

4. If 1 car is going faster than another traveling in the same direction, can they have the same velocity? Why or why
not?
Help please 15 points ??? ASAP
Answer:
No, because objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. The average velocity of an object moving in a constant direction is calculated with the formula: velocity = distance/time.

A soccer ball is kicked at an angle of 40 degrees with an initial velocity of
14 m/s. What is the horizontal velocity in m/s? (Do not state units, and give
answers to the hundredths place.) *
Answer:
[tex]v_x=10.72\ m/s[/tex]
Explanation:
Projectile Motion
It's the type of motion that experiences an object launched near the Earth's surface and moves along a curved path exclusively under the action of gravity.
Being vo the initial speed of the object, and θ the initial launch angle, the two components of the velocity are given by:
[tex]v_x=v_o\cos\theta[/tex]
[tex]v_y=v_o\sin\theta-g.t[/tex]
The soccer ball is kicked at an angle of 40° with an initial speed of vo=14 m/s.
The horizontal component is:
[tex]v_x=14\cos 40^\circ[/tex]
Calculating:
[tex]v_x=14\cdot 0.766[/tex]
[tex]\mathbf{v_x=10.72\ m/s}[/tex]
Question 2 How can an induced magnet be made stronger? adding more secondary coils O adding more induction O adding more primary coils
Answer: adding a secondary coils
Explanation:
You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil. increasing the current flowing through the coil.
Induced magnet be made stronger,by adding more secondary coils.
Increasing the magnetic field applied to the magnetizable material in turn makes its own magnetic field stronger. Similarly, wrapping with thicker wire has the same effect, but by increasing the current. Like a widening river, a thicker conductor allows more current through.
What is secondary coil ?"Coil such that current is induced in it by passing a current through the primary coil. secondary winding, secondary. coil - reactor consisting of a spiral of insulated wire that introduces inductance into a circuit."
What is magnetic field ?"A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field."

It takes much more force to blast a soft ball 50 meters than it does to hit a golf ball 50 meters.
Answer:
False
Explanation:
The softball is bigger, but it is lighter, which means it has a better chance of getting farther way faster with a lighter amount of force. On the other hand, the golfball is heavier, which would take more force to move it a certain distance.
Answer: false
Explanation:
• Defines what the “natural” states of motion are, either at rest and constant
velocity. In essence, the first law sets up the basis to define what accelerated
motion is, which we address with Newton’s 2nd law.
• Defines the type of coordinate systems so that Newton’s laws are valid. These

A 3kg ball is swung on the end of a 1m long string that is twirled with a speed of 3.2 m/s. What is the centripetal acceleration acting on the ball?
Answer:
The centripetal acceleration acting on the ball is 10.24 m/s²
Explanation:
Given;
mass of the ball, m = 3 kg
radius of the swing arm, r = 1 m
speed of the ball, v = 3.2 m/s
centripetal acceleration is given by;
a = v² / r
a = (3.2)² / 1
a = 10.24 m/s²
Therefore, the centripetal acceleration acting on the ball is 10.24 m/s²
