Question 13 A simple pendulum has a length of 0.532 m. The pendulum bob of mass 40.0 x 10-3 kg is displaced 2.50 x 10-2 m from equilibrium and released. It then moves with simple harmonic motion (S.H.M.). a) i. Determine the time period of the pendulum. ii. Determine the maximum acceleration of the pendulum bob. iii. Sketch a graph to show how the acceleration varies with displacement for the pendulum. The graph should show both axes with labels and unit, appropriate values indicated on each axis and a line of best fit. iv. Determine the total kinetic and potential energy of the pendulum bob
