1. The problem statement, all variables and given/known data A 73 kg high jumper leaves the ground with a vertical velocity of 7.6 m/s. How high can he jump? The acceleration of gravity is 9.8 m/s^2. 2. Relevant equations mgh1 + 1/2mv1^2 = mgh2 + 1/2mv2^2 3. The attempt at a solution 0 + 1/2(7.6)^2 = 9.8(h2) + 1/2(v2)^2 How can you solve this when you two unknowns? Does v1 = 7.6 also apply to v2? Am I using the right equation?
