Three balls A,B and C each of mass m and...

Three balls `A,B` and `C` each of mass `m` and same size,are placed along same line on smooth horizontal surface.A is given a velocity `u` towards `B` as shown.If coefficient of restitution for collision between `A` and `B` is `(1)/(2)` and between `B` and `C` is `(1)/(3)`.Assuming all the collisions to be head on choose the correct options: (A) Final velocity of `A` is `(u)/(4),` (B) Final velocity of `B` is `(u)/(4)` (C) Final velocity of `C` is `(u)/(2),` (D) Total energy loss is `(5)/(16)m u^(2)`
