Masses of the bodies A,B and C are `1` kg, `2` kg and `3` kg respectively. There is no friction between the ground and the bodies. Initially ball A is moving with a avelocity `20` m/s collieds inelhastically `(e=0.5)` with the ball B,which was initially at rest. The ball B further colides elasticaly to the block C (at rest), and then C collides elastically to the will in front. Find the velocities of the three blocks after all collisions occurred.

Answer

`"["v_(A)=0m//s,v_(B)=2m//s,v_(c)=8m//s"]"`
