Here's the question straight off my review sheet:
What coefficient of friction is needed to prevent a person from sliding when standing on the train which is accelerating at 7 m/s^2?
The way I think i'm supposed to do it to find the force exerted on the person and then use that to solve for coefficient of friction. My problem is that i don't know how to do this w/o the mass of the person.
Also according to my calculations, this train is accelerating faster than a porsche 911 turbo(0-60: porsche - 4.2s, train - 3.83s). Even if a train could accelerate that fast, it would matter what the coefficient of friction is seeing as how anyone standing would be thrown on their @ss
Thanks
