## Homework Statement

A mass of 500 g is attached to the bottom of an unstretched spring attached to the ceiling, and has a spring constant 10 N/m. The mass is then released. What is the net work done on the mass between the point where it was released and the lowest point that it reaches?

## Homework Equations

Wnet= F.d

## The Attempt at a Solution

The point at which it is released, v=0 and the lowest point is a turning point therefore v=0. So Wnet=delta K= 0 as velocity is 0 both times. Would the work done be 0 J then? Thanks in advance for any help!
