Ed is pushing with a force of 203.3 N at an angle of 0 = 57.5 degrees with respect to the vertical and Al is pushing with a force of 87.3 N at an angle of Ø = 36.1 degrees with respect to the horizontal. If the couch has a mass of 74 kg and the coefficients of static and kinetic friction between the couch and the floor are us = 0.53, and uk = 0.39, what is the magnitude of the force of friction exerted by the floor on the couch?
