Chapter 6, Problem 34P

GO In Fig. 6-37, a slab of mass m₁= 40 kg rests on a frictionless floor, and a block of mass m₂= 10 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force $\stackrel{\to }{F}$ of magnitude 100 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?
