A 3 kg and a 5 kg box rest side-by-side on a smooth, level floor. A horizontal force of 32 N is applied to the 3 kg box pushing it against the 5 kg box, and, as a result, both boxes slide along the floor. What is the magnitude of the contact force between the two boxes? Assume no friction.
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. What is the magnitude of the acceleration of the upper block? What is the magnitude of the acceleration of the lower block?
A block M₁ of mass 10.5 kg sits on top of a larger block M₂ of mass 20.5 kg which sits on a flat surface. The kinetic friction coefficient between the upper and lower block is 0.415.
The kinetic friction coefficient between the lower block and the flat surface is 0.115. A horizontal force F = 91 N pushes against the upper block, causing it to slide. The friction
