Re: segway license, turn signals, and no sidewalks?
Quote:
F=ma
a = V^2-V0^2/2x
a = 0^2-12.5^2/2(18.6)
a = 8.2 ft/s^2
F=ma = (250)(8.2) = 2050 lbf/ft

Some how some way you botched your calculation. I don't know where you got 250 but I don't think that's right. First of all if you want to calculate force using ft/s^2 you have to use the slugs as mass. I checked and the heaviest segway is only 3 slugs and a 200 pound person is 6 slugs. So its more like 72 pounds of force.
