Academics

A 1.50 kg snowball is fired from a cliff 13.0 m high. The snowball's initial velocity of 14.0 m/s, directed 41.0° above the horizontal.

(a) How much work is done on the snowball by its weight during its flight to the ground below the cliff?

(b) What is the change in the gravitational potential energy of the snowball-Earth 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?
