16．(10分)如图所示，质量m＝1 kg的小球用细线拴住，线长l＝0.5 m，细线所受拉力达到　　F＝18 N时就会被拉断.当小球从图示位置释放后摆到悬点的正下方时，细线恰好被拉断.若此时小球距水平地面的高度h＝5 m，重力加速度g＝10 m/s²，求小球落地处到地面上P点的距离.(P点在悬点的正下方)

15．(10分)射击运动员沿水平方向对准正前方100 m处的竖直靶板射击，第一发子弹射在靶上的A点，经测量计算，得知子弹飞行速度为500 m/s，第二发子弹击中A点正下方5 cm处的E点，求第二发子弹飞行速度。(不计空气影响，g＝10 m/s²)

14．(10分)雨伞边缘至竖直伞柄的水平距离为r且高出地面h，现竖直伞柄以角速度ω旋转，使雨滴自边缘甩出后落至地面成一大圆圈，求此圆半径．

12、三个同学根据不同的实验条件，进行了“探究平抛运动规律”的实验：

(1)甲同学采用如图(1)所示的装置。用小锤打击弹性金属片，金属片把A球沿水平方向弹出，同时B球被松开，自由下落，观察到两球同时落地，改变小锤打击的力度，即改变A球被弹出时的速度，两球仍然同时落地，这说明______　　　　　　　　　　　　　　　　　　　 _。

(2)乙同学采用如图(2)所示的装置。两个相同的弧形轨道M、N，分别用于发射小铁球 P、Q，其中N的末端与可看作光滑的水平板相切；两轨道上端分别装有电磁铁C、D；调节电磁铁C、D的高度，使AC＝BD，从而保证小铁球P、Q在轨道出口处的水平初速度v₀相等，现将小铁球P、Q分别吸在电磁铁C、D上，然后切断电源，使两小铁球能以相同的初速度v₀同时分别从轨道M、N的下端射出。实验可观察到的现象应是____　　　 __ 。仅仅改变弧形轨道M的高度，重复上述实验，仍能观察到相同的现象，这说明______________　　 　　　　　　　　　　。
