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.

Two similar trains are moving along the equational line with same speed but in opposite direction. Then :

Four smooth steel balls of equal mass at rest are free to move along a straight line without friction. The first ball is given a velocity of 0.4 m/s . It collides head on with the second elastically, the second one similarly with the third and so on. The velocity of the last ball is

A steel ball of radius 2 cm is at rest on a frictionless surface. Another ball of radius 4 cm moving at a velocity of 81 cm//see collides elast cally with first ball. After collision the smaller ball moves with speed of
