Compute all parts of given question:
Question: A 0.60-kg basketball is dropped out of the window that is 6.0 m above the ground. The ball is caught by a person whose hands are 1.2 m above the ground.
Part A: How much work is done on the ball by its weight?
Part B: What is the gravitational potential energy of the basketball, relative to the ground when it is released?
Part C: What is the gravitational potential energy of the basketball when it is caught?
I want help to find the gravitational potential energy of the basketball, relative to the ground when it is released.
