A 60 kg basketball is dropped out of a window which is 6.1 m above the ground. The ball is caught by the person whose hands are 1.5 m above the ground.

Q1. How much work is done on ball by its weight? Determine the gravitational potential energy of the basketball, as relative to the ground, when it is:

a) When it is released and
b) When it is caught?

Q2. describe how is the change (PE1 – PE0) in the ball’s gravitational energy associated to the work-done by its weight?
