The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. What is the average acceleration of the car?

Verified Answer :

Average acceleration is how much the car increases (on average) per second.  So, since it increases by 30 m/s in 8 s, then dividing 30 by 8 will give you an average acceleration of 3.75 m/s^2 (remember that acceleration is ever increasing, so the unit is s^2, not just s)

Hope this helps!

Answer : \(a=3.75\ m/s^2\)

Explanation :

Initial velocity of the car, u = 0 m/s

Final velocity of the car, v = 30 m/s          

Time taken, t = 8 s

Average acceleration of the car is defined as the change in velocity divided by time.

\(a=\dfrac{v-u}{t}\)

\(a=\dfrac{30\ m/s-0}{8\ s}\)

\(a=3.75\ m/s^2\)

Hence, this is the required solution.
