小车由自己设计,要求为：the car must roll down a 1m high ramp that is 2m in length,carrying a 0.2kg driver and a lidless dixie cup with 30ml of water.The water should still be there at the end of the slow down quickly after travelling 0.5m

The car will be evaluated on:
1) how fast it travels down the ramp-fater is better
2) how far it goes after travelling 0.5m on the flat-less is better
3)creativity and artistic design
Specifications:
The car must have a minimum length of 0.3m and a maximum length of 0/5m.The car must be between 0.15 and 0.25 wide.
Factors to consider:
-the diameter of the wheels,the width of the wheels,the centre of gravity,aerodynamics,friction of the wheels and axles,mass of the car,shock absorbers,does the car consistently travel straight?
符合这些要求的小车应该要怎么做,是怎么样的一部车子?有没有什么公式可以用来参考?

有一点,我怀疑我有一句话理解错了.（how far it goes after travelling 0.5m on the flat-less is better和at the end of the slow down quickly after travelling 0.5m from the bottom of the camp.
）
这部车子长度在0.3-0.5m,宽度在0.15-0.25m,滚下一个高1m,斜面长2m的斜坡,倾角为30°,小车在下了斜坡后应该很快在运动了0.5米后停下来.
考虑因素:——直径车轮,车轮的宽度,重心,空气动力学,车轮和轴的摩擦,大众汽车,减震器,汽车是否能一直连续运动.
我认为,本身是没有一个数据来限定这个车,主要是你做出来的这个车要能够动,这就是说车轮和车轴的摩擦要比很小,这样车轮才能滚动.然后要求校车在0.5米内能够停下来,就这要计算车轮与地面的摩擦力大小,是的当它以一定的速度滑下斜坡时,能够在0.5米内停下来（这个就是简单的匀减速运动的计算）.然后这个速度就是针对每一个特定的车所具有的,是需要评估的.然后用水不能够洒出来,这就需要你自己设计一个减震器,使得车子在拐角处水不会洒出来.车身的设计就是要在它规定的长宽内保证车子不会翻,保证一个稳定性.车子应该是一个受空气阻力比较小的流线型,这就考虑到设计.
