A block is released from a height H and slides down a frictionless curved surface (see figure). When reaching the bottom of the curved path, it moves on to a horizontal rough surface whose friction coefficient p(x) = a x. The quantity x represents the position along the rough surface and measures the distance to the bottom of the curved path whereas the coefficient a is a constant that makes the friction coefficient dimensionless.
