A bullet of mass m moving with velocity u passes through a wooden block of mass M = nm. The block is resting on a smooth horizontal floor. After passing through the block the velocity of bullet is v. Its velocity relative to block is
1
\(\frac{(1+n) v-u}{n}\)
2
\(\frac{n v-u}{n+1}\)
3
\(\frac{n v-u}{n+1}\)
4
\(\frac{(n+1) u+v}{2 n+1}\)
