Two hockey pucks (150g each) are travelling across the ice in a straight line. Puck 1 is travelling faster than Puck 2 and catches up with, and collides with, Puck 2. The initial velocity of Puck 1 was 3 ms-1 and the initial velocity of Puck 2 was 2 ms-1. After the collision, the speed of Puck 1 is 2 ms-1.
What is the magnitude of the impulse of Puck 1 on Puck 2?
