A 5.8 kg mass is attached to a spring with a stiffness of 490 N/m and is allowed to move along a friction-less horizontal surface. The mass is pulled back so that the spring is stretched 0.19 m from its equilibrium position. What will be the speed of the mass in m/s as it returns to the equilibrium position?
