A Measurement of "g" Listening to Falling Balls
White, J. A.; Medina, A.; Roman, F. L.; Velasco, S.
Physics Teacher, v45 n3 p175-177 Mar 2007
A ball placed on the edge of a horizontal table is hit with a pendulum and thrown over the floor. The fall time is measured by recording the sounds produced by the collisions with the pendulum and the floor. If the height of the ball with respect to the floor is known, one can determine the acceleration of gravity.
