A body of mass ‘m’ moving with a constant velocity ‘v’ strikes another body of same mass moving with same velocity but in opposite direction. The common velocity of both the bodies after collision is

Answer is Zero dear
Dont get confused with the optons :D

- m1v1+m2v2 = m1v1'+m2v2'
- mv+mv = mv'+mv'
- v = v'

Here, a body of mass m moving with a constant velocity v hits another body of the mass m moving with same velocity v but in the opposite direction, and sticks to it. We can write m

u

−m

As m

​
=m

=m and u

=u

=v
2mv=0
v=0

zero is answer
