Jimmy takes a red ball with a mass of 2.88 kg and throws it at a green ball with a mass of 4.35 kg using three methods. In the first method, the red ball is moving at 5.62 m/s, the green ball is stationary, and the collision is inelastic. In the second method, the red ball is moving at 5.62 m/s toward the north while the green ball is moving at 3.35 m/s at 25° west of south, and the collision is inelastic. In the third method, the red ball is moving at 5.62 m/s toward the north, the green ball is moving 3.35 m/s south, and the collision is elastic. For each of these methods, find the final velocity of the red ball and the green ball after they collide. Also what are the complete equations that describe the collision.

A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3.

Ball A, of mass 0.6kg, is initially moving to the right at 4 m/s. Ball B, of mass 1.8kg, is initially to the right of ball A and moving to the right at 2 m/s. After the two balls collide, ball B is moving at 3 m/s in the same direction as before. What is the velocity of ball A after this collision. Is this collision elastic or inelastic? What is the fractional change in kinetic energy?

A racquet ball with mass m = 0.252 kg is moving toward the wall
at v = 18.2 m/s and at an angle of θ = 25° with respect to the
horizontal. The ball makes a perfectly elastic collision with the
solid, frictionless wall and rebounds at the same angle with
respect to the horizontal. The ball is in contact with the wall for
t = 0.06 s.
