A truck is moving 14 m/s to the south. If it takes the truck 20 seconds to reduce its velocity to 10 m/s south, what is its acceleration?

-0.2m/s^2

Explanation:

What is given to us?
Initial velocity: 14m/s
Final velocity: 10m/s
Time: 20s

We can use the equation Vf=Vi+at

10=14+20(a)

-4=20(a)

-4/20=a

-0.2=a
