The speedometer of truck #1, moving to the east, read 90 km/h. It passes truck #2 that moves to the west at 90 km/h. What is the same between the two trucks?
Well the distance between the trucks and the point where they passed each other is the same for each until one changes velocity. The relative velocity is 180 of course.
The speed of the two trucks is the same, which is 90 km/h.
To determine what is the same between the two trucks, we need to consider the information provided.
1. Speed: The speedometer of truck #1 reads 90 km/h, while truck #2 moves at 90 km/h in the opposite direction. Therefore, the speed of both trucks is the same.
However, it is important to note that their velocities are not the same since velocity takes into account both speed and direction. In this case, truck #1 is moving to the east, while truck #2 is moving to the west. Their velocities will have the same magnitude (90 km/h) but opposite direction.
So, to summarize, the speed of truck #1 and truck #2 is the same, but their velocities are different due to their opposite directions.
