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/s^2.

6.38 (m/s^2)

Explanation:

Acceleartion is simply Δv/Δt, which we are both given. 26.8/4.2 = 6.38
