1. The problem statement, all variables and given/known data A skater jumps off a quarterpipe ramp and reaches 5m over the ramp. We can assume that he jumps in a vertical line. Find the speed the skater had before jumping off the ramp. 2. Relevant equations https://www.physicsforums.com/threads/introductory-physics-formulary.110015/ All the 1-D kinematic equations. It is not intended that you should use any more advanced equations than this. 3. The attempt at a solution It may seem like i haven't put in any effort, but i really have no clue as to how to solve this one. We have only been given the height, no speed, no acceleration and no start speed. I have never solved a problem like this where i've been given so little information.
