I am familiar with basic differential equations- but the equation is not seperable. It appears I'm having a math problem. If you really don't see why this problem could be confusing, could you just go ahead and show me how to solve it? All you've been doing is showing me basic equations and...
I'm sorry, but I'm really not understanding. Maybe you're referring to something in calculus I haven't come across yet, but I don't know how to integrate an expression with two differentials in it. I only know how to integrate expressions where there is an expression with the only variable being...
I don't know what I'm doing in all honesty. That's why I'm here. What I was asking is in order to carry out ads=vdv wouldn't you need a in terms of s. What I have is a in terms of v, so it doesn't matter what expression I am trying to integrate, it won't work.
Have you tried to solve the problem? It's impossible to solve for s with what you just told me. If it were that easy I'd have already done it. You come up with a=(u/m)(NR+mv^2/R), but you can't go further than that. The differential equation is unsolvable due to the v squared.
Ok, let me see if I can explain this well enough. There's a horizontal circular rod governing the motion of a collar having mass .75kg. The coefficient of kinetic friction is .3 and the collar is given an initial speed of 4 m/s starting at theta=0. I need to determine the arclength the collar...
