A block of mass 10kg from rest experiences a constant force of 10N for 5 seconds across a level frictionless surface, after the force is taken off it travels 20 meters until it reaches an area with frictions, still on a level surface. It takes 8 seconds for the block to stop: What is the normal force of the block? What is the force due to kinetic friction? What is the coefficient of kinetic friction?
