The Problem

The photographer ... shame on him ... forgot to record the diameter of the ball. Deduce the value of the diameter in meters as accurately as possible. In solving this problem, use what you already know about projectile motion to investigate the motion of the bouncing ball. At first glance, it will seem as if insufficient information is given, as the scale of the video is not given and the surface on which the ball bounces cannot be seen. Consider yourself a Physics detective for this problem and come up with a winning strategy. Develop a method for solving the problem.

Data and Analysis

Carry out your method. Show all your work in Logger Pro. Label graphs clearly. Show how you determine the diameter of the ball.
