A small block of mass, m, sits on top of a larger block of mass, M. The coefficients of friction between the blocks are μk and μs where μs=3/2μk, but the larger block sits on a frictionless surface. An increasing force, F=ft in the x-direction is exerted on the smaller mass. a) Find the acceleration of larger block and the smaller block in the time before the smaller block slips off the larger block. b) the time in which the...

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...

Two blocks with masses m1 and m2 are connected by a massless string over a frictionless pulley. Block 1 sits on a frictionless horizontal surface and block 2 sits on a plane inclined at an angle θ above the horizontal. The coefficient of friction between block 2 and the incline is µk. The pulley, which is a uniform disk, has a mass mp and a radius R. When you release the blocks, both blocks slide without the string slipping on...

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...
