Dweirdo,
For the value of k, I summed the two springs together because they are acting in parallel (think how it would look if you took the two outside ends of the springs and brought them up and together-the cart would be suspended from both in parallel)
Hootenanny,
The motion was tracked...
Hi again,
Here's how I'm thinking of it.
If there was no dampening force there would be no change in momentum as measured every time the cart passes through equilibrium because the spring force is a conservative force. The only forces I'm looking for are the nonconservative forces which...
Hi, thanks for the response. Here's some answers that should help clarify things.
1)Yes, the springs are attached to the cart.
2)The initial and final energy of the cart was calculated as being the potential energy in the springs. 1/2kx^2 where x is the displacement from the equilibrium...
Hi everyone,
I am trying to calculate the coefficient of kinetic friction in two ways. One using energy and one using the principal of linear impulse and momentum. Not getting the same answer!
The system is a wheeled cart oscillating on a flat metal track between two springs. The motion...
