A race car's velocity increases from 3.6 m/s to 32.4 m/s over a 5-s time interval. What is its average acceleration?


    Velocity ansdspeed are the same number in this case since it keeps going in the same direction.

    According to the definition of acceleration,

    = (velocity change)/(time interval)
    = (speed change)/(time interval)

    = (32.4 - 3.6)/5 m/s^2
    = _______ m/s^2
