An ideal spring has a spring constant k = 20 N/m. The spring is suspended vertically. A 1.0-kg body is attached to the unstretched spring and released. It then performs oscillations.
(a) What is the magnitude of the acceleration of the body when the extension of the spring is a maximum?
(b) What is the maximum extension of the spring?
