An object of mass 0.40kg is attached to a horizontal ideal spring of force constant 80Nm−1. It oscillates with amplitude 0.10m about its equilibrium position. When the object is 0.06m away from equilibrium, answer the following.
(i) Calculate the total mechanical energy of the system.
(ii) Determine the potential energy of the object at this displacement.
(iii) Find the kinetic energy of the object at this displacement.
