Chapter 6, Problem 61(choose chapter or problem)
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 12 N must be applied to the top block. The assembly of blocks is now placed on a horizontal, frictionless table (Fig. 6-47). Find the magnitudes of (a) the maximum horizontal force that can be applied to the lower block so that the blocks will move together and (b) the resulting acceleration of the blocks. mtmb FFigure 6-47 61.
