During an old school drag race, a 1971 Ford Mustang Cobra jets past the ’67 Chevy Impala. It accelerates uniformly at 4.62 m/s² from rest to 69m/s. Immediately upon reaching 69m/s, the brakes are applied, and it stops 22.5 s later. Find the total distance traveled.

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –
