A block of mass “m” sits on a (bigger) block of mass “4m” that is on a frictionless table. The coefficients of friction between the two blocks are μs (static) and μk (kinetic). Assume that a horizontal force “F” is applied to the block on top (i.e. the smaller block with mass “m”). The force “F” is variable. The figure below is representative of this scenario. (You may use m = 10 kg, μs = 0.8, μk = 0.6, and...

A block of mass m = 2.0 kg is sitting stationary on a table. A horizontal force of magnitude F = 5.0 N is applied to the block, as shown. The coefficient of static friction is µS = 0.7, and the coefficient of kinetic friction is µK = 0.5. To the nearest 0.1 N, what is the magnitude of the force of friction between the block and the table?

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.

Two blocks are in contact on a table with kinetic friction coefficient of 0.2.A horizontal force is applied to the larger block, as shown in Figure. (a) If m1 2.3 kg, m2 =1.2kg, and F#3.2N, find the magnitude of the force between the two blocks. (b) if a force of the same magnitude F is applied to the smaller block but in the opposite direction, find the magnitude of the force between the blocks.
