To measure the static friction coefficient between a 1.9 kg block and a vertical wall. A spring (spring constant = 458 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 0.054 m, what is the coefficient of static friction?


mu*forcenormal=mg
mu*kx=mg
solve for mu.
