Q1. Two plane mirrors are separated by 140°, as drawing illustrates. If a ray strikes mirror M1 at the 75° angle of incidence, at what angle does it leave mirror M2?

Q2. The coefficient of kinetic friction is 0.50. A horizontal force of magnitude 87 N begins to pull directly on the block. In unit-vector notation, what are the resulting accelerations of (a) block and (b) slab?
