I have a question that asks to find the velocity of the object attached to a horizontal spring when it is halfway to equilibrium. I am given the mass, how far the spring was stretched, and the velocity of the spring when it was released.
I am unsure of what it means by halfway to equilibrium. Could i solve it by finding the initial kinetic energy?

Mechanical equilibrium - when the net force on the object is zero.

Questions for you:
Where would that be? Is it how far the spring was stretched?
If the stretch was L, then halfway to the equilibrium position should then be _____?

Can you clarify what you mean though, when you say you know the velocity of the spring when released. Is the object given an initial velocity? other than 0?

It said in the question that the spring undergoes simple harmonic motion, and achieves a maximum velocity of 1.5m/s.
 
No, it says 1.5 m/s is the speed when is released. Which needs some clarification. What was it doing before being released?
