A 1.5 kg block at rest on a tabletop is attached to a horizontal spring having constant 19.6 N/m. the spring is initially unstretched.cpnstant 20.0 N horizontal force is applied to the object causing the string to stretch. A) determine the speed of the object causing the moved 0.3m from equilibrium if the surface between the block and tabletop is frictionless. b) answer part  a) if the coefficient of kinetic friction between block and tabletop is 0.200.
