Rowan Introduction to Astronomy Activity #4: Momentum, Torque, Gravity/Weight Name: _______________________________________________ Score: _________________________________ 1. In the figure below, two balls collide. Ball A with mass m 1 = 30 kg is initially moving at 20 m/s. Ball B with mass m 2 = 9 kg is moving at 10 m/s. After the collision, ball A is moving at 10 m/s. How fast is ball B moving? Assume that we have an elastic collision between the two balls. Momentum is conserved so the momentum before the collision is equal to the momentum after the collision.
