Answer:

Explanation: Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Answer:

[tex]\huge\boxed{\sf Inverse \ Relation}[/tex]

Explanation:

According to Newton's Second Law Of Motion:

"The acceleration produced by the body is directly proportional to the force acting on the body and inversely proportional to mass."

So, The Mathematical Form will be:

Acceleration ∝ [tex]\sf \frac{1}{mass}[/tex]

So, Acceleration and mass are inversely proportional. This means that Greater the mass, Smaller will be the acceleration produced and vice versa.

Answer:

C. While all societies use natural resources, they do not use them in

the same way

Explanation:

Natural resources are endowments by nature in a particular place. Different regions of the world have either similar or varied types of resources.

Therefore, with cultural influences and climate, these resources are put into different forms of usage.

A snow blower is more powerful because it's easier, and it moves large amounts of snow easily. Shoveling uses all of your power. It can be difficult and it takes a long time to get the snow off of your lawn.

Therefore, using a snow blower is more powerful than using a shovel.

Answer:

H = 234.85m

Explanation:

Using the formula for calculating range to find the maximum height

Range R = U√2H/g

U is the speed = 13m/s

H is the max height

R is the distance covered in horizontal direction

g is the acceleration

Substitute the given values as shown;

90 = 13√2H/9.8

90/13 = √2H/9.8

6.923 = √2H/9.8

6.923² = 2H/9.8

2H = 6.923²  *  9.8

2H = 469.70

H = 469.70/2

H = 234.85m

Hence the top level was 234.85m high

You need to first measure the angle of descent, i.e. the angle the hill makes with the ground. Then identify the forces acting on the sled, split them up into horizontal and vertical components, or into components that are parallel and perpendicular to the hill, and use Newton's second law to determine the components of the sled's acceleration vector.

There are at least 2 forces acting on the sled:

• its weight, pointing downward with magnitude W = m g

• the normal force, pointing perpendicular to the hill and away from the ground with mag. N

The question doesn't specify, but there might also be friction to consider, indicated in the attachment by the vector F pointing parallel to the slope of the hill and opposing the direction of the sled's motion with mag. F.

Splitting up the forces into parallel/perpendicular components is less work. By Newton's second law, the net force (denoted with ∑ or "sigma" here) in a particular direction is equal to the mass of the sled times its acceleration in that direction:

∑ (//) = W (//) = m a (//)

∑ (⟂) = W (⟂) + N = m a (⟂)

where, for instance, W (//) denotes the component of the sled's weight in the direction parallel to the hill, while a (⟂) denotes the component of the sled's acceleration perpendicular to the hill. If there is friction, you need to add -F to the first equation.

If the hill makes an angle of θ with flat ground, then W makes the same angle with the hill so that

W (//) = -m g sin(θ)

W (⟂) = -m g cos(θ)

So we have

-m g sin(θ) = m a (//)   →   a (//) = -g sin(θ)

-m g cos(θ) + N = m a (⟂)   →   a (⟂) = 0

where the last equality follows from the fact that the normal force exactly opposes the perpendicular component of the weight. This is because the sled is moving along the slope of the hill, and not into the air or into the ground.

Then the acceleration vector is

a = a (//)

with magnitude

||a|| = a = g sin(θ).

Answer:

To find the acceleration, you do 20N/50kg = 0.4 m/s^2

Explanation:

example: a = F/m = 10/2 = 5 m/s2

Answer:

The time spent in air by the car is 2.19 s

The height of the cliff is 58.5 m

Explanation:

Given;

initial velocity of the car, u = 16 m/s

horizontal distance traveled, R = 35 m

The horizontal distance or range of a projectile is given as;

R = vt

where;

t is the time spent in air by the projectile

t = R/v

t = 35 / 16

t = 2.19 s

The height of the cliff is given as;

h = ut + ¹/₂gt²

h = (16 x 2.19) + ¹/₂(9.8)(2.19)²

h = 58.5 m

Answer:

The thrown football has Potential or stored Energy, PE, by virtue of its position in the air and the ability for it to fall by itself. The thrown football also has Kinetic Energy, KE, given that the ball is in motion and requires an equal and opposite amount of energy to stop it. Both the PE and the KE  are forms of Mechanical Energy, ME and the Mechanical Energy of the football is equal to the sum of its Potential and Kinetic Energy. That is ME = PE + KE

Explanation:

Potential energy, PE, is the energy that is the held or stored energy of a body such that the body is able to do work without the addition of energy from an external source

A thrown football that has an elevation or height above the floor level has the capacity to come back down and bounce on the floor without the presence of assistance at the topmost height of the football. Therefore, the thrown football has potential energy, given to it by the thrower

Kinetic Energy, KE, is the energy possessed by a moving that comes from the motion of the object

Given that the thrown football is in motion, it posses kinetic energy

Therefore, the thrown football possesses both potential energy and kinetic energy which are forms of mechanical energy ME

The combined energy of the football is therefore called the Mechanical Energy ME of the ball which is the sum of the potential and kinetic energies of the football, given as follows;

The Mechanical Energy of the football = The Potential Energy of the football + The Kinetic Energy of the football

∴ ME = PE + KE

Answer:

1. Range = 153.42 m.

2. Maximum height = 54.78 m

3. Time of flight = 6.69 s

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

1. Determination of the range.

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

Acceleration due to gravity (g) = 9.8 ms¯²

Range (R) =?

The range i.e how far the ball went can be obtained as follow:

R = u² Sine 2θ /g

R = 40² × Sine (2×55) / 9.8

R = 1600 × Sine 110 / 9.8

R = 1600 × 0.9397 /9.8

R = 153.42 m

2. Determination of the maximum height.

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

Acceleration due to gravity (g) = 9.8 ms¯²

Maximum height (H) =?

H = u² Sine² θ / 2g

H = 40² × (Sine 55)² / 2 × 9.8

H = 1600 × (0.8192) ² / 19.6

H = 54.78 m

3. Determination of the time of flight

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

Acceleration due to gravity (g) = 9.8 ms¯²

Time of flight (T) =?

T = 2u Sine θ / g

T = 2 × 40 × Sine 55 / 9.8

T = 80 × 0.8192 / 9.8

T = 6.69 s

Answer:

The answer is D

Explanation:

Answer:

The magnitude of the work performed by the mover is 1863 J.

Explanation:

The work can be found using the following equation:

[tex] W = F*d [/tex]

Where:

F: is the force

d: is the displacement = 8.1 m

First, we need to find the net force in the horizontal direction, as follows:

[tex] \Sigma F_{x} = ma = 0 [/tex]

a = 0 since the mover slides a refrigerator at a constant velocity.

[tex] F_{x} = F_{f} = -230 N [/tex]

[tex]F_{f}[/tex]: is the friction force.

Then, the work is:

[tex] W = F*d = -230 N*8.1 m = -1863 J [/tex]    

Therefore, the magnitude of the work performed by the mover is 1863 J.

I hope it helps you!                              

Answer:

F = 4.8 N

Explanation:

Given that,

Mass of the curtain, m = 1.2 kg

Acceleration of the pull, a = 4 m/s²

We need to find the force she exerts on the curtain.

We know that,

F = ma

Put al the values,

F = 1.2 kg × 4 m/s²

= 4.8 N

So, the force is 4.8 N.

Answer:

Explanation:

Let the direction of the south be -y

Let the direction of the east be +x

The displacement is gotten by using the pythagoras theorem as shown;

Let d be the displacement;

d² = x² + y²

Given

x = 45 yards

y = -80 yards

Substitute the given values into the expression;

d² = x² + y²

d² = 45² + (-80)²

d² = 2025 + 6400

d² = 8425

d = √8425

d = 91.79 yards

Hence the total displacement of the player is 91.79 yards

Answer:

White dwarf

Explanation:

It depends on two factors: The direction of application of force and the coefficient of friction, [tex]\mu[/tex], between the object and the surface on which the object is placed.

If the direction of application of force is vertically downwards, then the object will not move for any value of [tex]\mu[/tex].

If the coefficient of friction is zero, [tex]\mu=0[/tex], then any value of force that is not in a vertically downward direction, the object will move.

If the direction of application of force is not vertically downwards, then it depends on the value of frictional force.

Answer:

1. and 2. If the buoyant force is greater than the object's weight, the object rises to the surface and floats. If the buoyant force is less than the object's weight, the object sinks. If the buoyant force equals the object's weight, the object can remain suspended at its present depth.

3. When the buoyant force equals one ton, it will sink no further. When any boat displaces a weight of water equal to its own weight, it floats. This is often called the “principle of flotation” where a floating object displaces a weight of fluid equal to its own weight.
