A car starts from rest at a stop light and reaches 20 m/s in 3.5 s. Determine the acceleration of the car.


A. 3.5 m/s^2

B. 5.7 m/s^2

C. 20 m/s^2

D. 70 m/s^2

Respuesta :

We know, acceleration = change in velocity / Time
a = 20 - 0  / 3.5
a = 20 / 3.5
a = 5.7 m/s2

In short, Your Answer would be Option B

Hope this helps!

The answer is 5.7 m/s^2
