An object is released from rest and falls in free fall motion. The speed v of the object after it has fallen a distance y is given by v2 = 2gy. In an experiment, v and y are measured and the measured values are used to calculate g. If the percent uncertainty in the measured value of v is 5.19% and the percent uncertainty in the measured value of y is 5.00%, what is the percent uncertainty in the calculated value of g?
