Yes, actually, I did the problem two different ways, both of which ended up with the same answer. The first way, which i thought was wrong, was this.
Ff=2m (so now I'm accelerating, and there is no force-of-train)
9.8mu=2m
u=2m/9.8m
u still equals .2
Ft is, um, Force of the train. I didn't know what else to label it as. The only thing I was confused about is whether or not the Force of the train on me is it's acceleration times my mass.
I have a question for homework, and this is a high school physics class. The question reads:
Suppose that you are standing on a train accelerating at 2.0m/s^2. What minimum coefficient of static friction must exist between your feet and the floor if you are not to slide?
I've drawn a free...
