A shell of mass 'M' moving with velocity 'V' suddenly explodes into two fragments. One of the mass 'm' is reduced to rest. Find the velocity of the other fragment.

Question

\[(a)\;\frac{(M-m)}{MV} \quad (b)\;\bigg(\frac{m}{M+m}\bigg)V \quad (c)\;\bigg(\frac{m}{M-m}\bigg)V \quad(d)\;\frac{MV}{M-m} \]
