zener diode with (threshold??) voltage of 2V i.e. anything over 2v is aloud to pass back through

just out of interest, apart from euler and the improved euler methods?

how would I get the lagrangian equation as a function of time though? n/m I used Runge-Kutta method thanks :D

I've done it :D Using Runge-Kutta method.. but now I need to work out vectors for the forces...

I did, it's here http://mathbin.net/45802

I've got this now, but how do I get them as functions of time? http://mathbin.net/45802

I've got this now http://mathbin.net/45802

But doesn't that forumula 2pi*sqrt(L/g) only work for small amplitudes this is a fairly large one at pi/2 radians :P

I had another go at it, this is as far as I got: Thanks so far btw! :) A mass of 2 kg is dropped vertically into a frictionless slide located in the x-y plane. The mass enters with zero velocity at (-5,5) and exits traveling horizontally at (0,0). Assuming the slide to be perfectly...

I know, I attempted it and failed hard :P Surely there must be an easy way?

I don't know where to start since the acceleration is constantly changing. I did, but this is an extension to the work.

I can't find anything on the internet about this... How is it done? I've got a smooth curve given by these parametric equations: y = 5cos( theta )+5; x = 5sin( theta ) taking g = 9.81 how can I model the position of the ball as a function of time? Or how can I model it so that i can...

ok, so v is tangential velocity. so how do I go from tangential velocity to position (x,y) at time t?

centre is 0,5 but yeah, it's a sliding point mass. the difference between the two is the same through out? how? becuase it would have 0 GPE at 0,0 :S

ok, so the parametric equation for a circle radius 5 origin 0,5 is y = 5cos( \theta )+5; x = 5sin( \theta ) or in Cartesian form (x)^2 + (y-5)^2 = 25 would the velocity at any given y be v^2 = 2 g (y-5) or would that just be the y component of the velocity?
