A block of mass m = 2 kg and initial velocity v = 5 m/s runs into and compresses a spring of spring constant k = 50 N/m. After compressing the spring, the spring returns to its equilibrium position, expelling the block. The surface between the block and floor is frictionless. How long is the block in contact with the spring?
