Determine the functional form of Phi(t) and the frequency of a pendulum bob whose mass is m and is attached to a massess rod of length l. Assume that the bob oscillates in the limit of small oscillations. Start with ml(second derivative of phi with respect to t)=F and the following initial conditions t=0, phi=chi derivative of phi with respect to t=0.
