Consider the acceleration of a good sports car in real life.

(1) Pick a certain car model, which could be the one you are driving, or the one you wish you were --- and search online for its acceleration data, which is usually given in the number of seconds it takes to reach 60 miles per hour.

(2) Convert that data to the standard units of acceleration in the SI system, which is m/s². To do so, first substitute 1600 m for 1 mile and 3600 s for 1 hour, so miles per hour becomes meters per second. For example, 100 mi/h = (100 x 1600 m) / (3600 s) = 44.4 m/s. Next, use acceleration = change in speed / change in time. Divide the speed in m/s you just calculated by the number of seconds to reach that speed (which you find online) to obtain the acceleration. For example, if it takes 10 seconds to reach 100 mi/h (which is equal to 44.44 m/s), then the acceleration would be (44.4 m/s) / (10 s) = 4.44 m/s².

(3) Theoretically, the maximum acceleration ANY car can possibly get, with rubber tires on dry, level concrete road, is equal to 1g (g = acceleration of gravity, or 9.8 m/s²). Does the performance of your dream car exceed what's theoretically possible?
