A mass is attached to a spring of spring constant 60.0 N/m along a horizontal, frictionless surface. The spring is initially stretched by a force of 5.0 N on the mass and let go. It takes the mass .50s to go back to its equilibrium position when it's oscillating. What is the amplitude of the oscillating mass? an explanation of how to find this would be most helpful!! Thank you!
