14、解析:可将物体的运动过程视为匀变速直线运动。规定向下方向为正,则物体的

初速度为V0=-10m/s,g=10m/s2

则据h=,则有:

∴物体刚掉下时离地1275m。

13、解析:(1)由题意得摩托车匀加速运动最长时间

位移,所以摩托车在达最大速度之前没有追上卡车。则追上卡车前二者速度相等是间距最大,设从开始经过t2时间速度相等,最大间距为Sm ,于是有

  最大间距

(2)设从开始经过t时间摩托车追上卡车,则有

解得  t=120s

12.(1)公共汽车在司机的反应时间内前进的距离x1 = vt =10 m

(2)公共汽车从司机发现小狗至停止的时间内前进的距离x2 = x1 + vt/2 = 50 m

(3)因为x2>x,所以小狗不安全。

小狗不发生危险,可以采用如下的一些方式:① 小狗沿车的前进方向在4.5s内跑出5m以上的距离。② 小狗沿垂直车运动的方向在4.5s内跑出的距离超过车的宽度。

(本题的答案不唯一,只要学生论述言之有理,即可得分)

10.B 解析:物体B从开始到停下来所用的时间=5s,在此时间内B前进的距离sB==25m,A前进的距离sA= vAt =20m。故此时刻AB相距(5+7)m=12m,所以再经过3s A才能追上B,故物体A追上物体B所用的时间为8s。故B选项正确。

9.AC  解析:如果立即做匀加速直线运动,t1=2s内的位移=20m>18m,

  此时汽车的速度为12m/s<12.5m/s,汽车没有超速,A项正确;如果立即做匀减速运动,速度减为零需要时间s,此过程通过的位移为

  6.4m,C项正确、D项错误。
