A horizontal force F1=75 N and a force F2=16.5 N, acting at an angle θ to the horizontal, are applied to a block of mass m=2.5 kg. The coefficient of kinetic friction between the block and the surface is μk=0.2. The block is moving to the right.
(a) Solve numerically for the magnitude of the normal force, FN in Newtons, that acts on the block if θ=30°.
(b) Solve numerically for the magnitude of the acceleration of the block, a in m/s2, if θ=30°.
