Question

The velocities of two bodies get interchanged after the collision. Their masses are ​

Answer 1

Explanation:

HEY mate.......

➡️For a head-on collision with a stationary object of equal mass, the projectile will come to rest and the target will move off with equal velocity.

➡️Hence, the velocities are interchanged

➡️i.e. the speeds are interchanged which in turn interchanges the momentum.

➡️Also, if target have some velocity then the faster body slows down and the slower body speed up.

Answer 2

Explanation:

For a head-on collision with a stationary object of equal mass, the projectile will come to rest and the target will move off with equal velocity. Hence, the velocities are interchanged i.e. the speeds are interchanged which in turn interchanges the momentum.
