I was given this following question:

You are on a skateboard moving at 12 m/s [N]. You throw a crumpled piece of paper at 9.0 m/s [N 25 degrees E] at an angle of 35 degrees above the horizontal. The vertical displacement is zero. Where will it land in relation to the starting point?

This one's brutal, and it is required to be answered soon :S

I hope anyone has the "know-how" as to help derive an answer out of this question. Any help is appreciated, and a great thanks in advanced...
