    A 23.0 kg block is initially at rest on a horizontal surface. A horizontal force of 70.0 N is required to set the block in motion. After it is in motion, a horizontal force of 56.0 N is required to keep the block moving with constant speed. Find the coefficients of static and kinetic friction from this information.
