Assume a 8 lb weight stretches a spring 6 inches. Recall that the gravity constant for standard units is 32f t/s2 (also recall that a pound is a unit of force (weight) not mass). Find an expression which represents the position of the mass with respect to its equilibrium position if we assume the effect of damping is negligible and there are no external forces acting on the mass, where the mass is initially stretched an addition 3 in beyond the equilibrium position an is released with an initial velocity of 2 ft/s.
