You are trying to slide a sofa across a horizontal floor. The mass of the sofa is 2.0 x 102kg, and you need to exert a force of 3.5 x 102N to make it just begin to move. (a) Calculate the coefficient of static friction between the floor and the sofa.(b) After it starts moving, the sofa reaches a speed of 2.0 m/s after 5.0 s. Calculate the coefficient of kinetic friction between the sofa and the floor.
