炮弹能上到的最高高度是h=1/2gt^2=8000m；所以最少为8000m。
2、先假设初速度为Vo，方向为与地面成的角度为O则有：
1/2gt^2=h代入数据有1/2*10*t^2=20解得时间t=2s；
向上初速度为：V=VoSinO-gt，由刚好到达20m处得，到达20m处时V=0；
则有VoSinO=gt=10*2=20m/s；
水平方向速度为匀速运动速度为VoCosO，水平位移为30m，则有VoCosOt=30即VoCosO=15
由VoCosO=15、VoSinO=20可求出Vo=25，O=53°
1.vsin30=400m/s
(vsin30)*2=2gh
解得 h=8000m
2.（vsinθ）*2=2gh
vsinθ=gt
x=vcosθt
解得tanθ=3
v=20（15）*1/2/3m/s
打点计时器的工作原理是利用交流电的频率50HZ，振针频率也是50HZ，这与电压无关。。。。3min汽车行了3*60*20=3600m再加上相隔1000m共计4600m。设加速度为a、加速行了x用时t、匀速行了s用时3*610-t。。。。则：{x=(1/2)at^2，at=30，s=30*(3*60-t)，x+s=4600}联立解得：t=60，所以a=0.5
