Q. Two identical mass $M$ moving with velocity $u_{1}$ and $u_{2}$ collide perfectly inelastically. The loss in energy is
A) $\frac{M}{2}\left( u_{2} - u_{1} \right)^{2}$
B) $\frac{M}{2}\left( u_{1} - u_{2} \right)^{2}$
C) $\frac{M}{4}\left( u_{1} - u_{2} \right)^{2}$
D) $\frac{M}{4}\left( u_{2} - u_{1} \right)^{2}$
Explanation
The correct answer is Option C: $\frac{M}{4}\left( u_{1} - u_{2} \right)^{2}$.
