I live about 10 miles from there, and am the corporate buyer for my org. The
DE State Police (not highway patrol) are the ones that staff security, and
it's more like 1-3 on duty at a time. 3 being during holiday times.
There used to be "bus tours"" of Asians from NYC that would all wait in
line to buy 2 iphones a day, every day, 7 days a week. There'd be a line of
100-300 every day, for about a year straight. Store employees told me they
would start at the Christiana store in the AM, then hit 2 more or so on the
way back to NYC, each day, hitting each store for the limit-2 amount.
2-3 months ago, I was picking up some new hardware for work, and I
personally witnessed an Indian dude next to me buying a brick of 25 iPhone 5
's. My sales guy told me they were highest config, and that brick was
something like $20,000 worth. Said the guy came in once a week and bought a
brick for like the past month and change.

这还用想，当然是因为没税了。

没错。风姐也跟速度平方成正比。

因为动能跟速度平方成正比
为什么动能跟速度平方成正比？
首先，牛顿第二定律F=ma=m(dV/dt) 　　所以F*dt=mdV 　　两边乘V，有F*V*dt=mV*dV
而V*dt=ds,V*dV=d(1/2V^2) 　　所以F*ds=d(1/2mV^2) 　　两边积分，得∫F*ds
=(1/2)mV2^2-(1/2)mV1^2

动能和风阻什么关系
