Two identical ball bearings in contact with each other and resting on a frictionless table is hit head-on by another ball bearing of the same time moving initially with a speed \(v\) as shown in the figure.
If the collision is elastic, which of the following (figure) is a possible result after collision?
1. | 2. | ||
3. | 4. |
Step 1: Find the final velocities of the balls.
When two bodies of equal masses collide elastically. their velocities interchanged.
When ball 1 collides with ball-2, then the velocity of ball-1 becomes zero and the velocity of ball-2 becomes v, i.e., similarly.
when ball 2 collides will be 3
