Two equal masses m1 and m2 moving along the same straight line with velocities + 3 m/s and – 5m/s respectively, collide elastically. Their velocities after the collision will be respectively.
-
- –3 m/s & +5 m/s
- + 4 m/s for both
- –4 m/s & +4 m/s
- –5m/s & +3 m/s
Correct Option: D
In elastic collision, the velocities get inter changed if the colliding objects have equal masses.
