In each of the following real-world scenarios, determine which car has the greatest acceleration.

• A car at a traffic light starts from 0 m/s to 20 m/s in 4 seconds.

• A car on the highway speeds up from 20m/s to 40m/s in 3 seconds

• A car on a downhill slope slows down from 50m/s to stop in 2 seconds

• A car in a drag race starts from 0 m/s to 20m/s in 5 seconds
