To determine a car's maximum acceleration, you start from rest, press down hard on the accelerator pedal, and time how long it takes to get up to 26.8 m/s (about 60 miles per hour). It takes a powerful new electric car only 4.2 s to reach 26.8 m/s. What is the car's acceleration?
The car's acceleration is
m/s².
