Assume that the maximum horizontal distance you can throw a baseball (m = 0.145 kg) at an angle of α0 = 45∘ above the horizontal is 25 m. Part A) What is the kinetic energy of the baseball just after it leaves your hand? Ignore air resistance and the small distance the ball is above the ground when it leaves your hand. Take the zero of potential energy to be at the ground. Part B) At the ball's maximum height,...
