what is the average acceleration of a car that is initially at rest at a stop light and then accelerates to 24 m/s in 9.4 s?

Sagot :

Answer:

Below

Explanation:

To find the acceleration of the car you can use this formula :

     vf = vi + at OR a = v/t

I'm going to use the first one because it explains the steps more clearly :

vf = 24 m/s

vi = 0 m/s

t = 9.4 s

a = ?

     24m/s = 0 + (a)(9.4s)

     24m/s = a9.4

Divide both sides by 9.4

     a = 2.55319 m/s^2

Round to 3 sig figs

     a = 2.6 m/s^2

Hope this helps! Best of luck <3
