There is a box attached to a spring. The spring has a spring constant of 39 N/m. The ì 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?

  • physics -

    What you call "The ì" 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
