Question

A super ball of mass 0.1 kg is dropped from a height of 3.0 m above the floor. It bounces off the table and rises to a height of 2.6 m. This is an elastic collision similar to the carts with springs in your lab. Calculate the velocity of the hall the instant it reached ground level, v_1. Now use conservation of energy to calculate the velocity the ball must have after the collision at the instant it leaves the ground to reach a height of 2.6 m. These velocities are the initial and final velocities for the collision with the ground. Use them to calculate the change in momentum of the ball. Don't forget the directions are not the same so one will be +, the other -.
