A bullet of mass $m$ moving with velocity $v$ strikes a suspended wooden block of mass $M$. If the block rises to a $S$ height the initial velocity of the block will be

A body of mass $3 \,kg$ is under a constant force which causes a displacement s in metre in it, given by the relation $s=\frac{1}{3}t^2$, where $t$ is in second. Work done by the force in $2 s$ is

A particle moves with a velocity $(5i -3j + 6k) ms^{-1}$ undre the influence of a constant force $F=(10 i +10 j +20 K)N .$ The instantaneous power applied to the particle is
