I would like to thank both of you and taking the time out to answer my question. It has made me understand the derivation thoroughly.

Homework Statement Hi, If there is a series combination of a resistor and an initially charged capacitor, I know that the decay of the voltage is given by the equation v(t) = Ae^(-t/RC) where V(0) = A = V0. But i am unsure of how to get to this equations. Homework Equations If I assume...

OMG your a genius, it works perfectly. Thanks for the all the help man, this made me understand a lot of other problems too.

Ohh yeah I see it now so For forces in the x: mg sin x = mv^2/r cos x

Hopefully I go this right. For the forces in Y: Fn = mv^2/r sin X + mg cos X For forces in X: Fn Tan x = mv^2/ r cos x + mg sin x

Im so confused now, been working on it for over 2 hours almost in total. I'm assuming that there is a X and Y component of centripetal force that I don't understand, but I'm unsure of how I would draw it. I also realize that Fnet is equal to mv^2/r but I don't know what to do now. If you could...

Im not sure if I understand you correctly. But what i got is centripetal acceleration goes towards the circle, making it not the X-component of acc. But(assuming I understood right) it goes directly opposite the Fn force. So after I drew a new diagram I got: Fn = mv^2/r + mg cos x Fx = 0...

Homework Statement Derive the formula to calculate the angle at which the road should be banked to prevent the car from skidding(Ignore force of friction). Homework Equations tan x = v^2/gr ----- answer mv^2/r = fcThe Attempt at a Solution I get how they derived the formula due to this website...
