1.	Consider two trains A and B moving along parallel tracks with the same velocity in the same direction. Let the velocity of each train be 50kmh^(-1) due east. Calculate the relative velocities of the trains.
Answer» Solution :Relative VELOCITY of B with respect to A, `v_(BA)=v_(B)-v_(A)=50kmh^(-1)+(-50)KMH^(-1)=0kmh^(-1)` Similarly, relative velocity of A with respect to Bie. V is also zero. Thus each TRAIN will appear to be at rest with respect to the other.
