A 25 kg block is at rest on a horizontal surface. A horizontal force of 75 N is required to set the block in motion. When it is in motion a 60 N forced is required to keep the block moving with a constant speed. Find the coefficients of static and kinetic friction. Draw a force diagram and explain!

    That is not math, that is more science than math.

    That is not at all helpful. It's math/physics

    Static friction: 75/ ( 25 * 9.8 ) = .31 Kinetic friction: 60 / ( 25 * 9.8 ) = .24
