The table below shows the elapsed time when two different cars pass a 10, 20, 30, 40 and 50-meter mark on a test track.
a) For car 1, what is the average velocity (change in distance divided by change in time) between the 0 and 10-meter mark? Between the 0 and 50-meter mark? Between the 20 and 30-meter mark? Analyze the data to describe the motion of car 1.
b) How does the velocity of car 1 compare to that of car 2?
