A simple pendulum consists of a 0.6 kg mass attached to a 2.5 m long string, and is oscillating in simple harmonic motion. a. What is the period of the pendulum if the mass is doubled? b. What is the period of the pendulum if the length of the string is doubled? c. If the pendulum is moved to the moon, where the acceleration due to gravity is 1.6 m/s, how long should the string be for the period of the pendulum to be the same as it was on the Earth?
