A mass of 0.25 kg is attached to a spring whose spring constant is k = 25 N/m. The spring is compressed 0.35 m on a frictionless surface and released from rest. At what location is the kinetic energy at a maximum, what is the amount of kinetic energy, and what is the velocity of the mass at that point?
