Motion in a Straight Line

Question

Train A is moving along two parallel rail tracks towards north with speed … and train B is moving towards south with speed …. Velocity of train B with respect to A and velocity of ground with respect to B are (in …):

Accepted Answer

Option B. To find the velocity of Train B with respect to Train A, we have to subtract the velocity of Train A from the velocity of Train B, keeping in mind that they are moving in opposite directions. Since they are moving in opposite directions, the relative velocity is calculated by adding their magnitudes when converting into the same unit, which in this case is meters per second.
