Problem 9:   A horizontal force, F1 = 95 N, and a force, F2 = 19.7 N acting at an angle of θ to the horizontal, are applied to a block of mass m = 2.1 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right. Randomized VariablesF1 = 95 N F2 = 19.7 N m = 2.1 kg Part (a)  Solve numerically for the magnitude of the normal force, FN in Newtons, that acts on the block if θ = 30°.   Part (b)  Solve numerically for the magnitude of acceleration
