1. The problem statement, all variables and given/known data an outfielder throws a 2.15 kg baseball at a speed of 113 m/s and an initial angle of 11.2 degrees. What is the kinetic energy of the ball at the highest point of its motion. 2. Relevant equations KE = 1/2mv^2 KE(initial) + PE(initial) = KE (final) + PE (final) 3. The attempt at a solution KE = 1/2 (2.15 kg) (113* sin 11.2)^2 KE =517.866 My method seems too simple. Should I be using the conservation of energy equation and if so, how should I go about doing it?
