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.

m/s

(b) What is that speed if, instead, the launch angle is 41.0° below the horizontal?

m/s

(c) What is that speed if the mass is changed to 2.50 kg

m/s
