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?
