1.	The graph shows position as a function of time for two trains running on parallel tracks. Which statement is true ? A. At time `t_B`, both trains have the same velocity.B. Both trains have the same velocity at some time after `t_B`C. Both trains have the same velocity at some time before `t_B`.D. Somewhere on the graph, both trains have the same acceleration.
Answer» Correct Answer - C At some time before `t_B`, slope of `B` will be equal to slope of `A` Acceleration of `A` is zero always whereas that of `B` is not zero.
