A block of mass m is moving along positive x direction on a smooth horizontal surface with velocity u. It enters a rough horizontal region at x = 0. The coefficient of friction in this rough region varies according to `mu = ax`, where a is a positive constant and x is displacement of the block in the rough region. Find the time for which the block will slide in this rough region
