A simple pendulum consists of a 0.8-
kg bob connected to a massless
inextensible cord with a length L = 1.4
m. The bob is set into motion and its
angular displacement is given by 0(t)
=0.11cos(wt), where e is in radians
%3D
and t is in seconds. Take g = 9.8
m/s^2, determine the mechanical
energy of this pendulum.
