Compare the acceleration nk*qx(clj+f- 64- c zxyfuy.ish 16szof a motorcy/ez; trq jr22scle that accelerates from 80km/h to 90km/h with the acceleration of a bicycle that accele2tsj;ze2/ rq rrates from rest to 10km/h in the same time.
参考答案: The acceleration
of both the motorcycle and the bicycle are the same, since the same change in
velocity occurred during the same time interval. If you do a further
calculation, you will find that the distance traveled by the motorcycle during
the acceleration is 17 times the distance traveled by the bicycle.
