Find work done and gravitational potential energy of a ball.
A 60 kg basketball is dropped out of a window that is 6.10 m above the ground. The ball is caught by a person whose hands are 1.50 m above the ground.
(a) How much work is completed on the ball by its weight? What is the gravitational potential energy of the basketball, relative to the ground, when it is?
(b) When it is released and
(c) When it is caught?
(d) How is the change (PE1 - PE0) in the ball's
gravitational energy related to the work completed by its weight?
