    Kirchhoff's Rules, system of equation problem

    Thanksl that is exactly what has happened, I get an infinite amount of solutions so, Does that mean I should always use an equation generated by the junction rule?

    Kirchhoff's Rules, system of equation problem

    I came up with three equations, to find three different currents in a DC circuit, using Kirchhoff's loop rule, but when I solved them as a matrix in my calculator the bottom row becomes all zero's and the first two rows do not appear to be in "rref" form. I solved the system of equations by...

    Pendulum work/energy problem

    I am still having trouble with the last part of the problem. In the event that there is no mechanical energy lost (100% conserved) how high up the ramp will the cart rise? I can't seem to figure out how to go about this part of the problem. We are only looking at work/energy in the problem...

    Pendulum work/energy problem

    What would then happen to the cart. I know it get sent on it's way up the ramp but how does this motion change if there is no loss to the mechanical energy in the system. dextercioby: The conversion is the amount of energy changed from mechanical to some other form (ie. heat).

    Pendulum work/energy problem

    I am having dificulty with a problem involving a pendulum. Basically the pendulum is at rest at a specified hight. The pendulum is then allowed to swing and it strikes a cart at the base of it's arc and then the cart rolls up a ramp while the pendulum swings back to a lesser height than...
