In the figure, a slab of mass m1 = 40 kg rests on a frictionless floor, and a block of mass m2 = 9 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 of magnitude 103 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?
