A spring with a force constant of 100 N/m is used to push a 0.27 kg block of wood against a wall. (a) Find the minimum compression of the spring needed to keep the block from falling, given that the coefficient of static friction between the block and the wall is 0.53.

Answer 1

You need a horizontal force of F = m g/.53 to keep the block from sliding.

F = k x
solve for x
