Suppose you are determining the velocity of a baseball by measuring the distance it travels, X, in a time T. You measure X to be 32.5 m ± 0.5 m, and you measure T to be 10 seconds. Assume that T is known "exactly", i. e. the error in T is so small that it can be neglected. Compute the velocity V = X/T, and also compute ζV, the uncertainty in V.
