Chapter 8, Problem 8(choose chapter or problem)
A 1.50 kg snowball is fired from a cliff 12.5 m high. The snowballs initial velocity is 14.0 m/s, directed 41.0 above the horizontal. (a) How much work is done on the snowball by the gravitational force during its flight to the flat ground below the cliff? (b) What is the change in the gravitational potential energy of the snowballEarth system during the flight? (c) If that gravitational potential energy is taken to be zero at the height of the cliff, what is its value when the snowball reaches the ground?
