A block of mass m is pulled by a force of constant power P placed on a rough horizontal plane. The friction coefficient between the block and the surface is `mu`. Then

The maximum velocity of the block during the motion is `(P)/(mumg)`

The maximum velocity of the block during the motion is `(P)/(2mumg)`

The block's speed is never decreasing and finally becomes constant

The speed of the block first increases to a maximum value and then decreases
