A simple pendulum is constructed from a mass of 2 kg and a massless string of length 3.5 m. The pendulum is pulled 5.5 cm to the right and released to start the motion.
1. What is the period of the pendulum?
2. What would the new period of the pendulum be if the mass was doubled, the initial amplitude was cut in half, and the length of the pendulum was changed to 75% of it's original value?
