A block M1 of mass 10.0 kg sits on top of a larger block M2 of mass 20.0 kg which sits on a flat surface. The kinetic friction coefficient between the upper and lower block is 0.440. The kinetic friction coefficient between the lower block and the flat surface is 0.140. A horizontal force F= 97 N pushes against the upper block, causing it to slide. The friction force between the blocks then causes the lower block to slide also.
