• # question_answer A block of mass m is pulled by a constant power P placed on a rough horizontal plane. The friction coefficient between the block and the surface is $\text{I}{{\text{F}}_{\text{3}}}$. Maximum velocity of the block will be A)  $\frac{\mu p}{mg}$ B)  $\frac{\mu mg}{p}$ C)  $\mu mgp$ D) $\frac{p}{\mu mg}$

 [d] $\therefore P=F.V=constant$ When $F=\mu mg$ net force on block becomes zero, i.e., it has maximum or terminal velocity $\therefore$        $p=(\mu mg){{V}_{\max }}$ $\therefore$         ${{V}_{\max }}=\frac{P}{\mu mg}$
