Three object `A ,B` and `C` are kept is a straight frictionless horizontal surface . These have masses `m`, `2m` and `m` repectively . The object `A` move toward `B` with a speed `9 m//s ` and makes an elastic collision with a there after `B` makes complately inclesis with `C` . All motion over on the same straight line . Find the first speed of the object `C`
