Question

When a driver performs an emergency braking maneuver, both the driver’s reaction time and the deceleration of the car (after the driver applies the brakes), affects total stopping distance. Usually, the driver’s reaction time is assumed to be one second.

If a vehicle is going 72 mph, how many feet does the vehicle travel in one second?

Answer 1

105.6 feet

Explanation:

You would have to use stoichiometry to answer this question

72mi/1h · 1h/3600s · 5280ft/1mi

Multiply all the numerators, then multiply the denominators, and then divide the numerator by the denominator

380160/3600 = 105.6ft
