Question
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
%3D
angular displacement is given by e(t) = 0.11cos(wt), where e is in radians andt is
in seconds. Take g = 9.8 ms^2, determine the mechanical energy of this
%3D
pendulum.
