解题思路：两个飞镖都做平抛运动，并且从同一个点抛出，它们在水平方向上的匀速直线运动，和竖直方向上的自由落体运动，根据AB的位置分析可得两个飞镖的运动情况．

A、由于两个飞镖从同一个点抛出，水平位移相同，但是B在A的下面，说明B在竖直方向上的位移比A的大，由h=[1/2]gt² 可知，B的运动的时间要比A的长，所以A初速度要比B的大，所以A正确．
B、由A的分析可知A镖的初速度大，由于运动的时间很短，AB在竖直方向上的速度的差别很小，所以A的末速度要比B的末速度大，所以B错误．
C、由A的分析可知，C正确．
D、平抛运动的规律与物体的质量无关，所以不能判断AB质量的关系，故D错误．
故选AC．

点评：
本题考点： 平抛运动．

考点点评： AB两个飞镖都做平抛运动，并且从同一个点抛出，抓住它们的主要的差别就是初速度的大小不一样，所以运动的时间也就不一样了．

It is precisely because of the understanding of world outlook in the western world that almost certainly would lead to this kind of mentality. Moreover, in view of the fact that after the Renaissance in the fifteenth century, there was a fundamental change of Westerners’ attitudes towards the world and people; this was another transformation of the world outlook since the middle ages, and it was exactly this Renaissance influence that had developed such mentality traits of the westerners. A typical case among which was the compiling of encyclopedias and the westerners used them to classify knowledge into different categories for conducting scientific purposes; this was followed by the classification of majors and disciplines in universities. However, the core standpoint of the Chinese world outlook is “harmony in diversity”, it embodies the concordance of nature.
