A car traveling at 25 m/s speeds up to 30 m/s over a period of 5 seconds. The average acceleration of the car is?

a= 1 m/s^2

Explanation:

Average acceleration can be found by dividing the change in velocity by the time.

a= ΔV/t

The change in velocity is the difference of the final velocity and initial velocity.

ΔV= final velocity - initial velocity

The final velocity is 30 m/s and the initial velocity is 25 m/s

ΔV= 30 m/s- 25 m/s

ΔV= 5 m/s

The time is 5 seconds.

Now we know the two values.

ΔV= 5 m/s

t= 5 s

Substitute the values into the formula.

a= 5 m/s / 5 s

Divide.

a= 1 m/s/s

a= 1 m/s^2

The average acceleration of the car is 1 meter per second squared.
