Question

A simple pendulum of length 1.85 m and mass 1.51kg is set into motion oscillating back and forth. The maximum velocity achieved by the pendulum is 0.736 m/s. 1.From what initial height was the pendulum released? This height is the height above the lowest point in the pendulum swing. h = 2. What initial arclength was the pendulum pulled from equilibrium? s= 3.How many oscillations has the pendulum swung through during the first 15 seconds? Express your answer for the number of oscillations to 3 significant figures. N= 4.Assuming that the pendulum was pulled to the right and then released, what velocity would the pendulum bob have 21.2 seconds after release? You may assume that air resistance has a negligible effect on the pendulum. v=
