There is a box attached to a spring. The spring has a spring constant of 39 N/m. The ė between the box and the surface is 0.3. The box has a mass of 1 kg.

What is the maximum distance that the spring can be stretched from equilibrium before the box begins to slide back?

What you call "The ė" must be the static friction coefficient, mus.

Let X be the maxium displacement without slipping.

k*X = M*g*mus

k is the spring constant.
You know what g and M are.

Solve for X
