A1.35 kg block at rest on a tabletop is attached to a horizontal spring having constant 19.8 n/m. the spring is initially unstretched. a constant 23.8 n horizontal force is applied to the object causing the spring to stretch. the acceleration of gravity is 9.8 m/s 2 . 23.8 n 1.35 kg 19.8 n/m find the speed of the block after it has moved 0.236 m from equilibrium if the surface between block and tabletop is frictionless. answer in units of m/s.
