22.(10分)汽车刹车后,停止转动的轮胎在地面上发生滑动,可以明显的看出滑动的痕迹,即常说的刹车线,由刹车线长短可以得知汽车刹车前的速度大小,因此刹车线的长度是分析交通事故的一个重要依据。某一特殊路段的最高限制速度为40km/h,有一辆汽车遇紧急情况刹车,若汽车刹车后以7 m/s2的加速度运动,刹车线长14m,假如你是一位交警,请你通过计算求出汽车刹车前的速度v0 ,,来判断卡车是否超速违章行驶?
21.(9分)为了测量一高楼的高度,有人设计了如下实验:在一根长为l的绳两端各拴一重球,一人站在楼顶上,手执绳的上端使小球与楼顶平齐并无初速释放,使其自由下落,另一个人在楼下测量两球落地的时间差△t,即可根据l、△t、g得出楼的高度(不计空气阻力).从原理上讲,这个方案是否正确?若测得l=10m,△t=0.4s,g=10m/s2,试估算楼的高度.
