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.

Text Solution

Verified by Experts

The correct Answer is:
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.

Problems based on trains running on parallel track

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) .

Two trains, which are moving along different tracks in opposite directions, are put on the same track due to a mistake. Their drivers, on noticing the mistake, start slowing down the trains when the trains are 300 m apart. Graphs given in figure show their velocities as function of time as the trains slow down. The separation between the trains when both have stopped is

Train X running at 50 km h leaves station A at 11 a.m and train Y running at 90 km/h on parallel tracks leaves station A at 3 p.m. on the same day and in the same direction. After what distance from station A will both the trains be together?

The graph given show the position of two cars A and B as a function of time. The cars move along the x axis on parallel but separate tracks, so that they can pass each other's position without colliding. Which one of the following best describes the motion of car A as shown on the graphs?

The graph given shows the positions of two cars, A and B , as a function of time. The cars move along the x-axis on parallel but separate tracks, so that they can pass each other's position without colliding. At which instant in time is car-A overtaking the car-B ?

The graph given show the position of two cars A and B as a function of time. The cars move along the x axis on parallel but separate tracks, so that they can pass each other's position without colliding. At time t_(3) which car is moving faster?

There are two trains running on two parallel tracks. Length of each train is 120 m. When they are running in opposite directions, they cross each other in 4 seconds and when they are running in the same direction they cross in 12 seconds. What is the speed of the faster train?

Two trains whose speed is in the ratio of 3: 4 are going in opposite directions on parallel tracks. If each train takes 3 seconds to cross a pole, then in how much time will they cross each other?
