有图 求真相.
Suppose the roller coaster in Fig.6-38 (h1 = 37 m,h2 = 12 m,h3 = 20) passes point A with a speed of 1.20 m/s.If the average force of friction is equal to one third of its weight,with what speed will it reach point The distance traveled is 40.0 m.
中文:(h1 = 37 m,h2 = 12 m,h3 = 20) 一个物体.过了点A的时候的速度是1.2m/s.如果说平均破擦力等于3分之1的这个物体的重量.这个物体到达B的时候是什么速度?2点之间的距离为40m.

翻译有点问题吧!
distance表示的是在AB之间经过的路程,而跟距离应该用straight line 或者 straight distance,This sentence “The distance traveled is 40.0 m.” should be translated definitely in “滑轮经过了40M的路程” not “AB 亮点之间的距离是40M” There are lots of differences between them.
直接用动能定理就可以解决啊.这题是高一的物理.
