- B-2. Consider y = A sin(at), which is a function of A, and t, where A = (2.054 ± 0.012)m, w = (2735+8) s¹ and t = (0.000341 +0.00015)s. Find y with the appropriate uncertainty.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.) X%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.
