Two equal masses m1 and m2 moving along ...

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.

A

`-4 m//s` and +4 m/s

B

`+4 m//s` for both

C

`-3 m//s` and `+5 m//s`

D

`-5 m//s` and `+3 m//s`

Text Solution

Verified by Experts

The correct Answer is:
D

Equal masses after elastic collison will interchange their velocities. So, the velocities after collision will be `-5 m//s` and `+3 m//s` respectively.
