[问答题]
Two cars emerge side by side from a tunnel. Car A is travetyjhec;*ja. ,k 3 ik0aling withe w;:jlz *yf- zf4+gpk a speed of 60km/h and has an acceleration of:fj;ef+4pwz k-lgy z * 40km/h/min . Car B has a speed of 40 km/h and has an acceleration of 60km/h/min . Which car is passing the other as they come out of the tunnel? Explain your reasoning.
参考答案:
If
the two cars emerge side by side, then the one moving faster is passing the
other one. Thus car A is passing car
B. With the acceleration data given for
the problem, the ensuing motion would be that car A would pull away from car B
for a time, but eventually car B would catch up to and pass car A.
