Two identical ball bearings in contact with each other and resting on a frictionless table are hit heat-on by another ball bearing of the same mass moving initially with a speed `V` as shown in figure. If the collision is elastic, which of the following (figure) is a possible result after collision ?A. B. C. D. |
|
Answer» (b) When two bodies of equal masses colides elastically their velocities are interchanges. When ball 1 collides with ball-2 then velocity of ball-1. `v_(1)` becomes zero and velocity of ball-2, `v_(2)` becomes v,i.e. similarity When ball 2 collides will ball 3 `{:(,v_(1)=0,Rightarrow v_(2)=v),(,v_(2)=0,v_(3)=v):}` |
