The force of friction is 32.65 N. The solution comes from first taking the sum of the forces in the normal. This yields the Normal force (N = Cos 32 degrees X Ff = Cos 32 X 110 N = 93.29 N) Next, we use the Normal force, plugging it into the accepted formula for Friction, Ff = u X N . This gives us: Ff = .35 X 93.29 N = 32.65 N.
