A block of mass m1= 4.00 kg moves on the surface of a horizontal
table. The coefficient of kinetic friction k between the table top
and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1
via a string that passes over a frictionless, massless pulley. The
two blocks start from rest and m2 drops by a distance L =1.75 m to
the floor.

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....
