Next replace particle 1 by a sledge hammer with mass m1 = 10 kg, particle 2 by a golf ball with a mass m2 = 10 g. Consider the elastic head-on collision between the hammer and the ball. The initial velocity of the sledge hammer is v1, the golf ball is initially at rest, v2 = 0 m/s. 1 2 v1 Estimate the approximate final speed v ′ 2 of the golf ball.
