1. The problem statement, all variables and given/known data A tennis ball of mass m = 0.087 kg and speed v = 43 m/s strikes a wall at a 45° angle and rebounds with the same speed at 45° (Fig. 7-29). What is the impulse given the wall? 2. Relevant equations Impulse = M x V Sin (theta) = opp/hyp 3. The attempt at a solution Impulse = .087(43) = 3.741 (at 45 degrees) Sin(45) = x / 3.741 x = 3.1832 Is the impulse given the wall. Is this corect?
