Question:

A body is suspended vertically from an ideal spring of spring constant 2.5 N/m. The spring is initially in its relaxed position. The body is then released and oscillates about its equilibrium position. The motion is described by
y = (4.0 cm) sin [(0.70 rad/s)t]
What is the maximum kinetic energy of the body?
