Physics Section 6.2 Calculate the momentum of collisions Consider a stationary ball being hit by a moving ball. After the collision both balls have a velocity and a momentum.

Law of Conservation of Momentum m1 v1,i + m2 v2,i = m1 v1,f + m2 v2,f m = mass v = velocity Total initial momentum = total final momentum The total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.

problem Two skaters are facing each other. They push off each other. The 1st skater has a mass of 55 kg and the 2nd skater’s mass is 75 kg. If the resulting velocity of the 1st skater is 2.5 m/s, find the velocity of the 2nd skater.

problem A cart with a mass of 1.8 kg is traveling with a velocity of 3.2 m/s. It collides head-on with a stationary cart with a mass of 1.2 kg. The 1st carts velocity after the collision is 1.1 m/s forward. Find the 2nd carts velocity after the collision.
