1.	Two identical ball bearing in contact each other and resting on a frictionless table are hit head - on by another ball bearing of the same mass moving intially with a speed c as shownin figure . If the collision is elastic mwhich of the following (figure ) is a possible result after collision ?
Answer» SOLUTION :When two bodies of equal MASSES collides elastically , their velocities are interchanged . When ball 1 collides with ball -2 ,then `v_(1)=0 and v_(2)=v` Similarly, when ball 2 collides with ball 3, `v_(2)=0 and v_(3) = v`
