From the prelab, you should have learned that the kinetic energy that your ball has immediately before striking the ground is identical to the potential energy it had before you released it from its initial height (assuming air resistance to be negligible, of course). You were also given the equation below to relate kinetic energy to momentum. 2 Use this information to calculate the momentum of the ball before and after it collides with the floor for each of your drops. Show ALL your calculations for one of your heights in the space provided and place all of your answers in Table 3.
