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° BELOW the horizontal. Using energy techniques ONLY, find the speed of the snowball as it reaches the ground below the cliff.
The Attempt at a Solution
I am not sure how to use the angle provided with either of these equations. Is there another equation that I could use?
