In the figure, a slab of mass m1 =
41 kg rests on a frictionless floor, and a block of
mass m2 = 11 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 106 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?
