Answer:
x = 65.68 [m]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f}^{2}=v_{o}^{2}-2*a*x[/tex]
where:
Vf = final velocity = 0 (comes to stop)
Vo = initial velocity = 17 [m/s]
a = desaceleration = -2.2 [m/s²]
x = displacement [m]
Now replacing, we have:
[tex](0)^{2}=(17)^{2}-2*(2.2)*x\\4.4*x = 289\\x = 65.68 [m][/tex]
A football is kicked with a speed of 18 m/s at an angle of 65° to the horizontal. How far does the football travel horizontally before it hits the ground?
The horizontal distance traveled by the football is determined as 25.33 m.
Horizontal distance traveled by the football
The horizontal distance traveled by the football is calculated as follows;
X = u²sin(2θ)/g
where;
u is the initial speedg is acceleration due to gravityX = (18² x sin(2 x 65))/9.8
X = 25.33 m
Thus, the horizontal distance traveled by the football is determined as 25.33 m.

Our atmosphere exerts a pressure of 14.7 lb/in2. What is the force on one square foot of the earth’s surface caused by the atmosphere
Answer:
The force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.
Explanation:
To force is given by:
[tex]F = P*A[/tex] (1)
Where:
P: is the pressure = 14.7 lb/in²
A: is the area = 1 m²
By entering the above values into equation (1) we have:
[tex]F = P*A = 14.7 \frac{lb}{in^{2}}*\frac{4.45 N}{1 lb}*\frac{1550 in^{2}}{1 m^{2}}*1 m^{2} = 101.4 kN [/tex]
Therefore, the force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.

One group approached their investigation by dropping a mass so it
fell vertically downward. They planned to measure the position of the
mass as it descended using a motion detector. They checked whether
the motion detector that they were using was sensitive enough to
capture the motion during the fall, and they were satisfied.
Given that they are measuring the motion (position, velocity, and
acceleration) of the mass, the students can only measure
gravitational potential energy and kinetic energy; any other form of
energy is undetectable. If they hope to see that energy is conserved
in this system, which of the following assumptions must be true (or
approximately true)?
Air Resistance is negligible
The initial vertical velocity of the mass is negligible.
Answer:
Air Resistance is negligible
Explanation:
If they hope to see that energy is conserved, then energy must not be gained or lost during the experiment. That is, loss due to air resistance must be negligible.
Answer:
air resistance negligible=true

A 615.00 kg race car is uniformly traveling around a circular race track. It takes the race car 20.00 seconds to do one lap around the 80.00 m radius circular track. What is the frequency of the race car's circular motion?
Answer:
The value is [tex]f = 0.05 \ Hz[/tex]
Explanation:
From the question we are told that
The mass of the car is [tex]m = 615 \ kg[/tex]
The period of the circular motion is [tex]T = 20 \ s[/tex]
The radius is [tex]r = 80 \ m/s[/tex]
Generally the frequency of the circular motion is
[tex]f = \frac{1}{T }[/tex]
=> [tex]f = \frac{1}{ 20 }[/tex]
=> [tex]f = 0.05 \ Hz[/tex]

How do u know that liquid exerts pressure ?
Answer:
All fluids exert pressure like the air inside a tire. The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions.

Answer:
As a plate sinks deep into a subduction zone, it heats and begins to melt, forming magma. If the magma reaches the surface it can build tall volcanic mountains.
Explanation:
Answer: " Most volcanoes form along plate boundaries. Volcanoes are common along tectonic plate boundaries where oceanic plates sink beneath other plates. As a plate sinks deep into a subduction zone, it heats and begins to melt, forming magma. If the magma reaches the surface it can build tall volcanic mountains. "
