situation, labeling all of the physical quantities given in the problem. Identify system in the sketch. 2. Draw a force diagram showing the forces exerted on the pendulum at its maximum amplitude and position-time and velocity-time graphs showing two full oscillations of the pendulum’s motion.

You have a simple pendulum that consists of a small metal ball attached to a long string. You push the ball so that at time t=0 it moves with a speed of 0.62 m/s through the equilibrium in the negative x-direction and continues oscillating with amplitude 16 cm. (a) Draw labeled position-time and velocity-time graphs for the first two periods of oscillation. (b) Determine the length of the string. 1. Draw a sketch of the situation, labeling all of the physical quantities given in the problem. Identify system in the sketch. 2. Draw a force diagram showing the forces exerted on the pendulum at its maximum amplitude and position-time and velocity-time graphs showing two full oscillations of the pendulum’s motion.
