In a science museum, you may have seen a Foucault pendulum, which is used to demonstrate the rotation of the earth. In one museum's pendulum, the 110 kg bob swings from a 16.6-m-long cable with an amplitude of 5.5 ∘.

Part A:What is the period of this pendulum?

Part B:What is the bob's maximum speed?

Part C:What is the pendulum's maximum kinetic energy?

Part D:When the bob is at its maximum displacement, how much higher is it than when it is at its equilibrium position?
