Question: Look at figure 1.8. If car A were to increase its speed to 60m/s, what would be the velocity of car A relative to car B. figure 1.8 is a picture of two car going different direction basically facing each other. Car a on the right is going at 40m/s and car b on the left is going at 60m/s. 60m/s - 60m/s = 0m/s is this right? Question #2: Two trains move on parallel tracks in opposite directions away from each other. one moves at the rate of 50m/s , while the other moves at 70m/s. what is the magnitude of the velocity of each train relative to the other? 50m/s - 70m/s = -20m/s 70m/s - 50m/s = 20m/s is this right? Thank You.
