Block A of mass mA is moving horizontally with speed Va along a frictionless surface
Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...

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....
