Question

The graph shows position as a function of time for two trains running on parallel tracks. Which statement is true (A) At time tB, both trains ha same velocity (B) Both trains have the same velocity at some time after tB (C) Both trains have the same velocity at some time before tB (D) Somewhere on the graph, both trains have the same acceleration

At some time before slope of tB will be equal to slope of A. Acceleration of A is zero always whereas that of B is not zero.

Q. The graph shows position as a function of time for two trains running on parallel tracks. Which statement is true

At time $t_{B}$ , both trains ha same velocity

Both trains have the same velocity at some time after $t_{B}$

Both trains have the same velocity at some time before $t_{B}$

Somewhere on the graph, both trains have the same acceleration

At some time before slope of $t_{B}$ will be equal to slope of $A$ .

Acceleration of $A$ is zero always whereas that of $B$ is not zero.

Q. The graph shows position as a function of time for two trains running on parallel tracks. Which statement is true

At time tB​, both trains ha same velocity

Both trains have the same velocity at some time after tB​

Both trains have the same velocity at some time before tB​

Somewhere on the graph, both trains have the same acceleration

At some time before slope of tB​ will be equal to slope of A. Acceleration of A is zero always whereas that of B is not zero.

At time $t_{B}$ , both trains ha same velocity

Both trains have the same velocity at some time after $t_{B}$
