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.

On the horizontal floor there are two boxes with masses m1 = 59 kg and m2 = 105 kg. The smaller box is pushed by 660 N. The smaller box pushes the larger box by 420 N. The smaller box acceleration is 2.5 m / s ^ 2 when the sliding coefficient between the box and the floor is 0.16. The situation remains the same, but the boxes exchange place. a) Determine the acceleration a of the larger box. b)...
