a slab of clay with a mass of 0.34 kg and velocity of 8 m/s hits a stationary toy car of mass 0.61 kg. If the clay hits and sticks to the car, what is the velocity of the clay and car after impact?

A 0.4 kg ball that is traveling at 8.1 m/s collides head-on with a 1.7 kg ball moving in a negative direction at a speed of 11.4 m/s. The 0.4 kg ball bounces backward at 15.2 m/s after the collision. Find the speed of the second ball after the collision.

2 balls collide head-on in an elastic collision. One ball has a mass of 4.0 kg and an initial velocity of 6.5 m/s. The second ball has a mass of 2.0 kg and its initial velocity is unknown. AFTER the collision the heavier ball has a velocity of 2.5 m/s. What is the velocity of the lighter ball before and after the collision?

An 87 kg wide receiver is running at 9.4 m/s and is hit by a 110 kg linebacker traveling in the opposite direction. After the collision, the two players move together in the receiver’s original direction at a speed of 1.6 m/s. How fast was the linebacker moving before the collision?
