A mass of 1 kg attached to a spring with a spring constant of 112 N/m oscillates horizontally on a smooth frictionless table with an amplitude of0.8 m.
(a) When the mass is 0.35 m away from equilibrium, determine its total mechanical energy.
(b) When the mass is 0.35 m away from equilibrium, determine the system's potential energy and the mass's kinetic energy, potential energy and kinetic energy.
(c) When the mass is 0.35 m away from equilibrium, determine the mass's kinetic energy when it is at the equilibrium point.
