NEET Physics Centre of Mass MCQ Question
Consider a one-dimensional elastic collision between two particles where the initial speed of particle 1 is v_1i = 3 m/s and its mass is m_1 = 2 kg. If the mass of particle 2 is m_2 = 3 kg and it is initially at rest, what is the final speed v_2f of particle 2 after the collision?
3.6 m/s
1.8 m/s
2.4 m/s
4.0 m/s
Correct Answer
Detailed Explanation
Using the relation m_1v_1i = m_1v_1f + m_2v_2f and the final velocity relation for elastic collisions, v_2f is calculated.
