Ok basically i need help to start off a question as a part of a research type thing. i need to find out the velocity of a 4 wheeled vehicle if string is wrapped around the rear axel of the vehicle multiple times and the string then extends up above the rear axel onto a pulley where a weight...

ok a new problem... basically now I'm looking at a normal 4 wheeled vehicle with some string attached to one axel which then goes up to the top of the vehicle on a pully where a weight sits at the top. Same as the question before, could you give me some pointers on where to start off the...

ok that was great. i should be fine from there on. with the acceleration, i don't think that i'll actually need that. just another question, is there anyway other measure which i could use to compare this vehicle with another vehicle that would be useful? like i can compare the velocity...

ok thanks for all that. So substituting the variables for linear kinetic energy i get KE = 1/2 x m x (r x Omega)^2 And the inertia formulas are: Inertia of a point = mr^2 Inertia of a disk = ½ x mr^2 Inertia of the end of a rod = 1/3 x mL^2 Ok, now for the change in gravitational...

ok thanks. wouldnt linear velocity = angular velocity x (Pi x D) where D is the diamater of the wheel.

Sorry if i didn't make it clear but the vehicle is at a standing start and essentially uses the weight to make the vehicle move. So I'm not entirely sure that I can get a velocity. Also, this isn't really a question it's more of a research type thing for a project before I make the vehicle...

i actually have no idea. In class we've only learned really basic physics type stuff. I know all the velocity equations like v = u +at and the 2 other ones like that and i know the basic inertia equation but i haven't really learned about this so i was wondering if you could give me a starting...

Basically, I need to find the mathematical modelling of a 2 wheeled vehicle if you like, that has a weight positioned at the top of the vehicle but inside the wheels if that makes sense. Essentially, when you let go of the wheel, the vehicle starts spinning until around half a revolution where...
