Two equal masses `m_1` and `m_2` moving along the same straight line with velocites `+3 m//s` and `- 5 m//s` respectively collide elastically. Their velocities after the collision will be respectively.

Two balls of equal masses movin with velocities 10m/s and -7m/s respectively collide elatically. There velocities after collision with be

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 identical balls A and B moving with velocities + 0.5 m/s and -0.3 .m/s respectively collide head-on elastically. The velocities of the ball A and B after collision will be respectively
