A car starts from rest and moves on a surface in which the coefficient of friction between the road and the tyres increases linearly with distance (x). The car moves with the maximum possible acceleration. The kinetic energy (E) of the car will depend on x as

A block of mass m starting from rest slides down a smooth inclined plane of gradient θ fixed in a lift moving upwards with an acceleration a0 as shown in figure. If the base of the inclined plane has length L the time taken by the block to slide from top to bottom of the inclined plane will be
