The period T of oscillation of a pendulum of length l is given by:T=2π√l/gIf the uncertainty in g is 2% and the uncertainty in l is 6%, what is the percentage uncertainty in T?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
