You know the main equations, so a good first step is to write them down.

You need to know - conservation of energy, work-energy relation, potential energy stored in a spring.

could you help me get started. With what equation? and I'm kinda confused on the 3 distances given.

x0, the equilibrium position.

x1, the initial position

x2, the final position

what's the problem?

If the mass were at x0, how much force would the spring exert on it?

The mass was at rest at x1 > x0, how much force does did spring exert on it? What was the total force on it? What do you deduce from

You moved the mass from x1 to x2 > x1 ...

My thought process: work is the change in energy which in this case is the change in potential (atleast I think it is). So I used the equation 1/2 kx squared.

What would you deduce from that information?
