A weight hanging from a flat horizontal surface in a spring-mass system exhibits simple harmonic motion behavior. The mass is 2 kg and there is no friction or loss of energy in the system, whilst the height of the horizontal surface from the ground is 10m. The system is in equilibrium, 5m from the ground, when the weight is motionless. If the weight is pulled down or pushed up and released, it would tend to oscillate freely. A force is applied and the motion of the mass can be described by: X =-2 cos nt a) Was the weight pulled down or pushed up before it was released? b) How far was the weight from the ceiling when it was released
