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
