Fexp = 4gx (6), where x is the distance from the zero position to the 061 actual position of the jockey weight. Using empirical data from measurements, time, volume and calibration of the tally we are able to use the listed equations below to calculate force on the deflector and rate change of momentum so that the results can then be plotted and analyzed. The equations used for these calculations are: Equations F = m a F = 06 (8 061785 Equation 1 Equation 2
