A block of mass mt=4.0 kg is put on top of a block of mass mb=5.0 kg. To cause the top
block to slip on the bottom one while the bottom one is held fixed, a horizontal force of at
least 12N must be applied to the top block. The assembly of blocks is now placed on a
horizontal, frictionless table (Fig. 6-51). Find the magnitudes of (a) the maximum horizontal
force F that can be applied to the lower block so that the blocks will move together and (b)
the resulting acceleration of the blocks.

It's on the 5th page.
I don't understand their equation for maximum horizontal force (M a = M μ_s g) and would appreciate if someone would explain it to me.
