Problem
A 0.20kg block is attached to a horizontal spring of force constant 80Nm−1. The system executes simple harmonic motion on a friction-less surface with an amplitude of 0.10m.
(a) Write the expression for the total mechanical energy of this system in terms of the given quantities.
(b) Determine the speed of the block when its displacement from the equilibrium position is 0.060m.
(c) Calculate the kinetic energy of the block at this instant.
