A

(a)all the balls will start moving to the right with speed 1/8 each

B

(b)all the six balls initially at rest will move on with speed V/6 each and two identical balls will come to rest

C

(c)two balls from the extreme right end will move on with speed V each and the remaining balls will remain at rest

STATEMENT - 1 : Two identical balls B and C lie on a horizontal smooth straight groove so that they are touching. A third identical ball A moves at a speed v along the groove. And collides with B as shown in figure. If the collisions are perfectly elastic, then after the collision, balls A and B will come to rest and ball C moves with velocity v to the right. because STATEMENT - 2 : In an elastic collision, linear momentum and kinetic energy are both conserved.

A stick of length L and mass M lies on a frictionless horizontal surface on which it is free to move in any way. A ball of mass m moving with speed v collides elastically with the stick as shown in the figure. If after the collision the ball comes to rest, then what would be the mass of the ball?
