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 v 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 4.80% and the percent uncertainty in the measured value of y is 5.00%, what is the percent uncertainty in the calculated value of g?

Question
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 v
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 4.80% and the percent uncertainty in the measured value of y is 5.00%, what is the
percent uncertainty in the calculated value of g? (Do not enter units for this answer.)
