Determine the impulse of the club C on the ball. Neglect the impulse caused by the ball’s weight while the club is striking the ball. Given: M 50 gm = 40 deg = d 20 m = g 9.81 m s 2 = Solution: First find the velocity v 1 Guesses v 1 1 m s = t 1s = Given 0 g 2 t 2 v 1 sin t + = dv 1 cos t = t v 1 Find tv 1 , = t 1.85 s = v 1 14.11
