A storage tank 24 m high is filled with gasoline. (Assume the tank is open and exposed to the atmosphere at the top.) (a) Find the gauge pressure at the bottom of the tank. (b) Calculate the magnitude of the force produced by the fluid that acts on a square access hatch at the bottom of the tank that measures 0.2 m by 0.2 m.

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
