Q. The graph shows position as a function of time for two trains running on parallel tracks. Which statement is true
Motion in a Straight Line
A
At time $t_B$, both trains ha same velocity
0%
B
Both trains have the same velocity at some time after $t_B$
0%
C
Both trains have the same velocity at some time before $t_B$
100%
D
Somewhere on the graph, both trains have the same acceleration
0%
Solution:
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.
