Question: A 60-kg basketball is dropped out of a window that is 6.1m above the ground. The ball is caught by a person whose h&s are 1.5m above the ground.
Find and explain following:
- When it is released
- When it is caught
- How is the change (PE1 – PE0) in the ball’s gravitational energy related to the work done by its weight?
- How much work is done on the ball by its weight? What is the gravitational potential energy of the basketball, relative to the ground, when it is?
