3. A person holds a 0.300 kg pomegranate at the top of a tower that is 96 m high. Another person holds a 0.800 kg melon next to an open window 32 m up the tower.
a. Draw a diagram to illustrate the situation. (1 point)
b. Calculate the gravitational potential energies of the melon and the pomegranate.
Which one has more potential energy? (2 points)c. At what height would the
pomegranate have the same potential energy as the melon? (1 point)d. If they are
dropped from their original heights at the same time, will the melon or the pomegranate
hit the ground first? Explain. (1 point)

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
