#### A powerful motorcycle can accelerate from rest to 26.8 m/s (100 km/h) in only 3.90 s.

(a) What is its average acceleration?

(b) How far does it travel in that time?

**SOLUTION:**

* Part (a).* The average acceleration of the motorcycle can be solved using the equation . Substitute the given into the equation. That is,

* Part (b). *The distance traveled is equal to the average velocity multiplied by the time of travel. That is,
