NEET Physics Kinetic Energy MCQ Question
Consider a diagram of a one-dimensional elastic collision between two bodies of equal mass, m1 and m2, where m1 = m2. If the initial velocity of m1 is v1i and m2 is at rest, what will be the final velocity of m1 after the collision?
v1f = 0
v1f = v1i
v1f = 2v1i
v1f = -v1i
Correct Answer
Detailed Explanation
In a one-dimensional elastic collision between two equal masses where one is initially at rest, the moving mass comes to rest and transfers its velocity to the stationary mass. Hence, v1f = 0.
