A Foucault pendulum is designed to demonstrate the effect of the Earth's rotation. A Foucault pendulum displayed in a museum is typically quite long, making the effect easier to see. Consider a Foucault pendulum of length 13.7 m with a 101-kg brass bob. It is set to swing with an amplitude of 3.35°.

a) What is the period of the pendulum?

b) What is the maximum kinetic energy of the pendulum?

c) What is the maximum speed of the pendulum?
