A mass is attached to a spring on a frictionless horizontal surface. The mass is pulled to stretch the spring by .1 m and then gently released. A short time later, as the mass passes during the equilibrium position, its speed is 1 m/s. What is the speed of the mass at the point where the spring is compressed with .05 m? What is the phase of the simple harmonic motion at that point, relative to a phase of zero at the time of the release?
