Stretched spring work

    1. The problem statement, all variables and given/known data
    Hi,

    I am thinking about a stretched spring with a mass on it. When the spring is fully extended and has just started to pull the mass back towards the equilibrium point, is the work positive or negative?

    2. Relevant equations


    3. The attempt at a solution

    I think as the spring is pulling the mass then work is positive but I'm not sure. Thanks!

    Please explain why you think it is positive.
