Record your data in the table below... Use equations (4), (5), (6), (7) and (8) to answer the following: 1. Calculate Va and vf . Note: v = Ax / I Where Axrepresents the diameter of the ball and t represents the time elapsed through the photogates. 2. Calculate the acceleration due to gravity using two different kinematic equations for each of the trials. (two calculations per trial) 3. Calculate the averages and standard deviations for the acceleration of gravity for both methods used
