lol..

i cahanged answer thrice.. did calculation msitake..

Now by conservation of momentum when A and C collides... velcoity of B=v_{0}/3

By conservation of energy

mv_{0}^{2}/2=1/2m(v_{0}/3)^{2}+2mx^{2}/2

x is speed of A and C

x= 2v_{0}/3

where V_{o}/3 is velocity in upward direction... so right componetn=v_{0}/√3

if not clear how velocity v_{0}/3

it is by conservation of momentum

finally when distance between A and C=0

then for the length to be L the velocities of all of them must be same

hence

mv_{0}=3mv^{'}
