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 is at rest on a plank whose angle can be varied. The angle is gradually increased from 0 deg. At 32.9°, the block starts to slide down the incline, traveling 2.80 m down the incline in 1.50 s. Calculate the coefficient of static friction between the block and the plank. Motion of a block If static friction acts on the block, does it move? What is its acceleration in this case?OK

the coefficient of static friction between block A and its
incline is 0.27. What must the minimum coefficient of static
friction between block B and its incline be if the blocks are in
equilibrium? The mass of block B is twice that of block A. If the
coefficient of friction is less than its minimum, in which
direction will the blocks slide?
