A 1.50 kg snowball is fired from a cliff 13.0 m high with an initial velocity of 14.0 m/s, directed 41.0° above the horizontal.
(a) Using energy techniques, rather than techniques of Chapter 4, find the speed of the snowball as it reaches the ground below the cliff.
(b) What is that speed if, instead, the launch angle is 41.0° below the horizontal?
(c) What is that speed if the mass is changed to 2.50 kg
