Can anyone clarify what Stanaz meant? I'd like to prove this problem using some kind of probability/binomial method. I don't understand his method or reasoning at all.

Homework Statement http://img10.imageshack.us/img10/9781/probs.jpg The Attempt at a Solution Hey guys, I understand how to find the static friction point (equate mv2/r to max static friction). However, I'm confused as to which direction (in to out or out to in) is the correct one ie. from...

So when this slipping stops, static friction takes effect? What I'm trying to find out is the reason it slips on the outside and stays in the inside. Thanks for your help, and for being so patient.

I'll show you the question and why I'm asking such a conceptual question. It's a bit of a weird one. I get how to find the radius of static friction but I don't understand the concept. I know it's best it walks from outside to inside. http://img257.imageshack.us/img257/2746/phs2.jpg

Great thanks a lot rl.bhat, I'll try have a crack at those properly now. Oh, I also have another quick conceptual question. Why is it when you are on a rotating surface that it goes from kinetic friction to static friction in the centre? I hope you understand what I mean. I'm saying as you...

Homework Statement http://img16.imageshack.us/img16/5889/physics.jpg The Attempt at a Solution Well for question 5, I'm having a bit of trouble recognising the reason why the space-pod doesn't move after they take their seats. I understand that the centre of mass doesn't change but I can't...

Hey Doc Al, shouldn't the force diagram have static friction going UP the hill. Because the static friction is what drives cars?
