Question

Two equal masses $m_{1}$ and $m_{2}$ moving along the same straight line with velocities $+3 \mathrm{~m} / \mathrm{s}$ and $-5 \mathrm{~m} / \mathrm{s}$ respectively collide elastically. Their velocities after the collision will be respectively\

Professor PC Thomas Classes · Answer

(d) : Equal masses after elastic collision interchange their velocities.\ $-5 \mathrm{~m} / \mathrm{s}$ and $+3 \mathrm{~m} / \mathrm{s}$.
