The plot shows the position (`x`) as a function of time (`t`) for two trains that run on a parallel track. Train `A` is next to train `B` at `t=0` and at `t=T_(0)`.

A

At `T_(0)` both the trains have the same velocity.

B

Both the trains speed up all the times.

C

Both trains have the same velocity at some time before `T_(0)`.

D

At `T_(0)` the trains have covered different distances

Text Solution

Verified by Experts

The correct Answer is:
C
Initially slope of `A` is more than `B` and initially finally slope of `A` is less. So speed of `A` is initially more than finally less than `B`. So somewhere in between their speeds become the same.
