The following question may look complicated, until one notices that simple basic physical principles can be used to solve it in one or two easy steps. Explain which principles are important and give the answer to the problem. Consider a pendulum hanging from the ceiling as shown. If it is given an initial displacement 0o and released from rest, after a long period of time, what average values of the kinetic and potential energies? (Assume that 0 is small, so that cos 0 ~ 1 – (1/2)02 ) are the o m
