Two stone slabs are stacked as shown below. The bottom one has mass m1 = 80 kg and the top one has mass m2 = 35 kg. The coefficient of static friction between the two, and between the bottom block and the floor, is µs = 0.8. What is the maximum force F you can apply to the bottom block m1 without pulling it out from under m2?

Two blocks (M1=5 kg and M2=3 kg) are
stacked on a frictionless surface but there is friction between
them. The coefficient of static friction between the blocks is
μs=0.6 and the coefficient of kinetic friction is
μk=0.3. If a person applies a horizontal force F=60 N to
M1, the blocks move. You do not know if the blocks slip
or accelerate together until you check.

m2 = 8 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 F of
magnitude 105 N begins to pull directly on the block, as shown. In
unit-vector notation, what are the resulting accelerations of
