A simple pendulum consists of a 0.8-kg bob connected to a massless
inextensible cord with a length L = 1.1 m. The bob is set into motion and its
angular displacement is given by 0(t) = 0.11cos(wt), where e is in radians and t is
in seconds. Take g = 9.8 m/s^2, determine the mechanical energy of this
pendulum.
