1. The problem statement, all variables and given/known data An athlete executing a long jump leaves the ground at a 25° angle and lands 6.30 m away. What was his take off speed? 2. Relevant equations (In all equations, X can be substituted for Y in entire equation) Vy= Voy + AyT Vy^2 = Voy + 2AyY Y=VoyT + (1/2)AyT^2 3. The attempt at a solution The answer is 8.98 m/s. I can't figure out how to do this problem, and need to understand this for an upcoming final. I have worked several other similar problems, but none without a known velocity and/or time. Any insight into how to even begin would be greatly appreciated.
