Problem
A body of mass 0.25kg is attached to an ideal horizontal spring and executes simple harmonic motion. The amplitude of oscillation is 10cm and the time period is 2.0s. At t=0, the displacement of the body is +6.0cm from the mean position and it is moving towards the mean position.
(i) Determine the angular frequency and the initial phase of the motion.
(ii) Calculate the kinetic energy and potential energy of the body at t=0.30s.
(iii) Find the total mechanical energy of the system.
