NEET Physics Angular Momentum MCQ Question
Type: MCQ-diagram based-Medium-Class 11
In the diagram shown above, two billiard balls of equal mass undergo a collision. If the initial velocity of the cue ball is 5 m/s and it comes to rest after the collision, what is the final velocity of the target ball?
A
5 m/s
B
0 m/s
C
2.5 m/s
D
10 m/s
Correct Answer
Option A
Detailed Explanation
In an elastic collision with equal masses, the cue ball transfers all its velocity to the target ball. Thus, the target ball will have a final velocity of 5 m/s.
