Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
We have an optional assignment for physics, shown below. I've already worked out the problems, but I'm not sure if I'm doing them correctly. I would really appreciate it if someone could explain how to solve the four questions below, as well as the principles behind them. Thank you!

Block 1, of unknown mass m1, is connected over an ideal (massless and frictionless)
pulley to block 2, of mass m2, as shown. Assume that the blocks accelerate as shown
with an acceleration of magnitude a and that the coefficient of kinetic friction between
block 2 and the plane is u.
a) (5 pts) Draw a freebody diagram for block 2.
b) (20 pts) In terms of m1, µ, a, 0, and any other relevant constants, find the mass of
block 2.

In the figure shown, the masses start from rest. The pulley
is massless and frictionless, and is attached to a support, but is free to turn
about its center. When the masses are released, the pulley rotates, and the
mass m1 falls through distance h in time 7. In terms of ml, g, h, T, and any
other relevant constants,
a) In terms of h, g, T, and any other relevant constants what is the
acceleration of mass m1 as it falls?
b) In terms of m1, h, g, t, what should the mass m2 be to produce this
acceleration?

A driver slams on his brakes, locks the wheels, and skids to a stop with a
constant frictional force. The coefficient of kinetic friction between the car and the tires is μ, and
the car skids a distance d. The mass of the car is m.
a) Draw a free body diagram for the car.
b) In terms of m, d, and µ, find the velocity that the car was traveling when the brakes were
applied.
c) A second identical car skids to a stop in distance d/2. Find the ratio of this car's speed to that
of the car in part (b).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8bb970b8-a3a7-4b4d-8269-3b7d72d993eb%2F77135766-c4be-497a-bfc3-3362fb6cbc06%2F3go4xs9_processed.jpeg&w=3840&q=75)
