50Hz 
Since the spark timer used in the lab was set at 50Hz per second, 50 dots are made for every secondwhich also means that one dot is 1/50th of a second, the velocity of the two pucks can be determined from this relationship with the use of , (to reduce rounding errors, all momentum calculations will be done in the base unit give:
