If we want to know the velocity of the train with respect to the car, we need to take the car as a stationary object. Let's imagine riding in the car using this distinction. For de niteness, suppose the direction ahead of the car is the y-direction and the direction perpendicular to that sweeping from the driver's left to right side is the x-direction. We can visualize trees, sign posts, and other objects rooted in the Earth rushing towards the car at 40 m s and then receding into the distance. That is to say, relative to the car these objects are moving with a velocity of- 40 m s in the y-direction. Likewise, if we were to see the train in the distance, it will appear to have a velocity containing both a left-right component and a coming towards us component. Since the two velocity directions, x and y, are perpendicular, we can de ne the train's velocity, mathematically as:-→ v...
