A car went from zero to 26.8 m/s (60 mi/h) in 3.275 s. find the magnitude of the car's acceleration.

The definition of acceleration is change in velocity per unit time. So:


a = \frac {\Delta v }{t}


You've been given values for the change in velocity (26.8m/s) and time (3.275 s). So turn on your calculator and plug away!
