So if I walk onto the freeway and get hit by a car with his cruise control set on 70 mph, I'm in fact getting hit with 0 force?
Doesn't help my hospital (or more likely funeral) bills, does it?
Or if he hits the brakes, we're talking negative force.
agree. the speed of an object is obviously a consideration in the amount of "force" in the collision. speed and mass. i dont need to be a physicist to know that.
i'd look to figure out first how fast she'd be falling after 30 feet, and then calculate the amount of "force" generated when she (50 lbs) strikes an stationary object at that speed.
i'm not going to use the internet to figure out how to do that right now (or ever, let's be real.)
so far it doesnt seem as if we have anybody qualified to make an accurate assessment of the collision, which is disheartening
are you nothing other than a contrarian? can you not solve the problem instead of pointing out flaws in the methodology of others?
