A powerful motorcycle can accelerate from rest to 22.2 m/s (80 km/h) in only 3.42 s. What is its average acceleration?

Respuesta :

Average acceleration is 6.49 m/s²

Explanation:

We have equation of motion v = u + at

     Initial velocity, u = 0 m/s

     Final velocity, v = 22.2 m/s    

     Time, t = 3.42 s

     Substituting

                      v = u + at  

                      22.2 = 0 + a x 3.42

                      a = 6.49 m/s²

     Acceleration is 6.49 m/s²

Average acceleration is 6.49 m/s²
