A simple pendulum consists of a bob of mass of 0.85 kg attached to a string of length 1.5 m. The pendulum is raised to point Q, which is 0.08 m above its lowest position, and released so that it oscillates with a small amplitude θ between the points P and Q as shown below. 1. Calculate the total energy of the oscillating system. 2. Determine the height at which the potential and kinetic energies are equal.
