The SI unit for length or distance is

• foot (ft)
• inch (in)
• mile (mi)
• meter (m)

In each of the following cases, determine which car has the greatest acceleration.

• starts from 0 m/s to 20 m/s in 4 seconds.
• speed up from 20m/s to 40m/s in 3 seconds
• slow down from 50m/s to stop in 2 seconds
• starts from 0 m/s to 20m/s in 5 seconds
