To measure the static friction coefficient between a 1.9 kg block and a vertical wall, the setup shown in the drawing is used.

A spring (spring constant = 418 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.070 m, what is the coefficient of static friction?
