A is only just keeping up with B, not pressing into it and accelerating it anymore. And if there's no more acceleration that means (by definition) that there's no more change in speed, so they will continue travelling at the same speed. | |

| Dec 16, 2022 at 6:29 | comment | added | Arun Bhardwaj | I also think if A has more velocity then B it would continue to apply force on B it means acceleration of A will decrease further an accelertion of B will increase but whne they will reach the common velocity the acceleration of B would me higher so it will sperarate from A so the contact force will decrease gradually and so the acceleration of B will decrease and acceleration of A will increase, so these line of A and B would never meet they would just cross each other again and again and they will "never" reach to a common velocity and acceleration(but their average over time can be same) | |
