To understand kinetic and static friction. A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is μs. The coefficient of kinetic friction is μk, with μk<μs. a- Suppose you want to move the block, but you want to push it with the least force possible to get it moving. With what force F must you be pushing the block just before the block begins to move? Express the...

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...
