Find acceleration of blocks F=40 N

A 20 kg block is initially at rest. A 75 N force is required to set the block in motion. After the motion a force of 60 N is applied to keep the block moving with constant speed. The coefficient of static friction is

A20 kg block is initally at rest. A 75 N force is required to set the block in motion. After the motion starts, a force of 60 N is required to keep the block moving with constant speed. The coefficient of static friction is
