Question

Snowball A 1.50 kg snowball is fired from a cliff11.0 m high with an initial velocity of14.0 m/s, directed 41.0° above the horizontal. (a) How muchwork is done on the snowball by the gravitational force during itsflight to the ground below the cliff?
1 J
(b) What is the change in the gravitational potential energy of thesnowball-Earth system during the flight?
2 J
(c) If that gravitational potential energy is taken to be zero atthe height of the cliff, what is its value when the snowballreaches the ground?
3 J
