If the initial velocity is +15.0 m/s and 5.0 s is required to slow down to +5.0 m/s, what was the car’s acceleration? Average acceleration is the rate of change of velocity, or the change in velocity per unit time. If an automobile slows from +26 m/s to +18 m/s in a period of 4.0 s, what was the average acceleration?
If an object traveled at 35 m/s for 20 s, it would travel the same distance in the same time as the previous example but in the second case, the object's velocity would always be 35 m/s.

What is (a) the average velocity of the car, and (b) the average speed of the car in m/s? (a) The average velocity of the car is zero (0 m/s) because xf=xi; the car ends up at the same place it starts.
