Elastic Collisions

Classical Mechanics Level 1

Six identical balls are lined in a straight groove made on a horizontal frictionless surface as shown below. Two similar balls each moving with velocity \(v\) collide with the row of 6 balls from left. What will happen after the collision, if the collisions are perfectly elastic?

Two balls from the right roll out with speed v each and the remaining balls will remain stationary One ball from the left rolls back with same speed v and one from right rolls forward with speed v All six balls roll out with speed v/6 each and the two colliding balls will come to rest One ball from the right rolls out with speed 2v and the remaining balls will remain at rest
