a 3.2 kg block is set on a horizontal table. one end of a spring is attached to the block and the other end is attached to a fixed support. The block is pulled back 41 cm from the spring's equilibrium position and released such that it oscillates horizontally. At the equilibrium position the velocity of the block is 2.2m/s. What is the spring constant of the spring? Assume frictionless table and massless spring
