• A 3.0 kg block of wood sits on a horizontal wooden floor. The larges force that can be applied before it starts moving is 14.7 N. Once the block starts moving, you only need 8.8N to keep it moving. • What is the coefficient of static friction? • What is the force of friction acting on the block if you push with a force of 6.8N [E]? Calculate the max static friction if you place a 2.1 kg on top of it • What is the kinetic coefficient of friction?
