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 E(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.

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 e(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.

A traveling wave on a taut string with a tension force T, is given by the wave
function: y(x,t) = 0.05sin(Tx-10Ttt), where x and y are in meters and t is in
seconds. If the linear mass density of the string is given by u = 0.01 kg/m, then
the tension force on the string is,
