The loss of kinetic energy during inelastic impact, is given by
(where m1 = Mass of the first body, m2 = Mass of the second body, u1 and u2 = Velocities of the first and second bodies respectively.)
A. $$\frac{{{{\text{m}}_1}{{\text{m}}_2}}}{{2\left( {{{\text{m}}_1} + {{\text{m}}_2}} \right)}}{\left( {{{\text{u}}_1} - {{\text{u}}_2}} \right)^2}$$
B. $$\frac{{2\left( {{{\text{m}}_1} + {{\text{m}}_2}} \right)}}{{{{\text{m}}_1}{{\text{m}}_2}}}{\left( {{{\text{u}}_1} - {{\text{u}}_2}} \right)^2}$$
C. $$\frac{{{{\text{m}}_1}{{\text{m}}_2}}}{{2\left( {{{\text{m}}_1} + {{\text{m}}_2}} \right)}}\left( {{\text{u}}_1^2 - {\text{u}}_2^2} \right)$$
D. $$\frac{{2\left( {{{\text{m}}_1} + {{\text{m}}_2}} \right)}}{{{{\text{m}}_1}{{\text{m}}_2}}}\left( {{\text{u}}_1^2 - {\text{u}}_2^2} \right)$$
