Ed is pushing with a force of 352.9 N at an angle of θ = 56.1 degrees with respect to the vertical and Al is pushing with a force of 146.3 N at an angle of ϕ = 37.3 degrees with respect to the horizontal. If the couch has a mass of 89 kg and the coefficients of static and kinetic friction between the couch and the floor are μs = 0.53, and μk = 0.39, what is the magnitude of the force of friction exerted by the floor on the couch? I am not understanding how to solve this. I think I need to use Newtons second law but I just dont know. Can someone please show me how to do this?
