Two equal masses m_(1) and m_(2) are moving along the same straight line with velocities 5ms^(-1) and -9 ms^(-1) respectively. If the collision is elastic, then calculate the velocities after the collision of m_(1) and m_(2), respectively

Two equal masses m_(1) and m_(2) are moving along the same straight li

1.	Two equal masses m_(1) and m_(2) are moving along the same straight line with velocities 5ms^(-1) and -9 ms^(-1) respectively. If the collision is elastic, then calculate the velocities after the collision of m_(1) and m_(2), respectively
Answer» `-9 ms^(-1) "and" 5 ms^(-1)` `-4 ms^(-1) "and" 10 ms^(-1)` `10 ms^(-1) "and" 0 ms^(-1)` `5 ms^(-1) "and" 1 ms^(-1)` Solution :When bodies has the same mass, (i.e. `m_1 = m_2`) Collide after the collision their velocities are EXCHANGED.
