Question
For a system of two colliding bodies with no external forces, the change in momentum of one body is:
Correct Answer
Option C is the correct answer.
Detailed Explanation
The lecture shows that from conservation of momentum, m1(v1f - v1i) = -m2(v2f - v2i). This means the change in momentum of one body is equal in magnitude but opposite in direction to the change in momentum of the other.
Hint
Think about the gun and bullet example.
