Problem
Two cars, X and Y, travel in a straight line with constant acceleration. Their positions are recorded every 1.0 s and listed below.
Time (s): 0 1 2 3 4
Position of X (m): 0 2 8 18 32
Position of Y (m): 0 3 12 27 48
Which car experiences the greater constant acceleration during the 0–4 s interval? State your choice and justify it using the data provided.
