Chapter 04, Problem 109
The central ideas in this problem are reviewed in Mutiple-Concept Example 9. One block rests upon a horizontal surface. A second identical block rests upon the first one. The coefficient of static friction between the blocks is the same as the coefficient of static friction between the lower block and the horizontal surface. A horizontal force is applied to the upper block, and its magnitude is slowly increased. When the force reaches 40.3 N, the upper block just begins to slide. The force is then removed from the upper block, and the blocks are returned to their original configuration. What is the magnitude of the horizontal force that should be applied to the lower block, so that it just begins to slide out from under the upper block?

A block M1 of mass 16.0 kgsits on top of a larger block M2 of mass 26.0 kg which sits on a flat surface. The kinetic friction coefficient between the upper and lower block is 0.400. The kinetic friction coefficient between the lower block and the flat surface is 0.100. A horizontal force F = 98 N pushes against the upper block, causing it to slide. The friction force between the blocks then causes the lower block to slide also....

A block of mass M is sitting on a friction-less horizontal surface. A second block of mass m is sitting on top of the first block. The (horizontal) interface between the two blocks is characterized by a static friction coefficient µ. The acceleration of gravity is g. Find the max horizontal force F that can be applied to the lower block such that the upper block does not slide off it.

A block of mass m1 sits on top of a larger block of mass2 which sits on a flat surface. The coefficient of kinetic friction between the upper and the lower blocks is u1, and that between the lower block and the flat surface is u2. A horizontal force F pushes against the upper block, causing it to slide; the friciton force between the blocks then cause the lower block to slide also. Find the acceleration of the upper block...
