Ed is pushing with a force of 362.8 N at an angle of 0 = 50.3 degrees with respect to the vertical and Al is pushing with a force of 126.8 N at an angle of o = 29 degrees with respect to the horizontal. If the couch has a mass of 98 kg and the coefficients of static and kinetic friction between the couch and the floor are u, = 0.52, and u = 0.39, what is the magnitude of the force of friction exerted by the floor on the couch?
