An apple of mass m = 0.13 kg falls out of a tree from a height h

Question:

An apple of mass m = 0.13 kg falls out of a tree from a height h = 3.2 m.

(a) What is the magnitude of the force of gravity, mg, acting on the apple?

(b) What is the apple's speed, v, just before it lands?

(c) Show that the force of gravity times the height, mgh, is equal to 1/2 mv2. (We shall investigate the significance of this result in Chapter 8.) Be sure to show that the dimensions are in agreement as well as the numerical values.
