Homework Help: Physics/Math

Posted by Technoboi11 on Wednesday, March 7, 2007 at 1:08am.

A 1.50 kg snowball is fired from a cliff 12.5 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?

I will be happy to critique your thinking on this.
