Two equal masses ${m_1}$ and ${m_2}$ moving along the same straight line with velocities $+ 3 \,m/s$ and $-5\, m/s$ respectively collide elastically. Their velocities after the collision will be respectively
Two equal masses ${m_1}$ and ${m_2}$ moving along the same straight line with velocities $+ 3 \,m/s$ and $-5\, m/s$ respectively collide elastically. Their velocities after the collision will be respectively
$+ 4\, m/s$ for both
$-3\, m/s$ and $+5\, m/s$
$-4\, m/s$ and $+ 4\, m/s$
$-5\, m/s$ and $+ 3\, m/s$
Two equal masses ${m_1}$ and ${m_2}$ moving along the same straight line with velocities $+ 3 \,m/s$ and $-5\, m/s$ respectively collide elastically. Their velocities after the collision will be respectively
As ${m_1} = {m_2}$ therefore after elastic collision velocities of masses get interchanged
i.e. velocity of mass ${m_1} = - 5\;m/s$ and velocity of mass ${m_2} = + 3\;m/s$
