I'm trying to find the equivalent "r" in terms of x and y for the acceleration. Yes, if it was a circle the acceleration would be v^2/r...but this surface we're talking about is not as nice as a circle.

The function describes the vertical displacement, y, compared to the horizontal displacement, x.

I started doing some physics today for the first time since school got out a few months ago. The period of inactivity was painfully apparent throughout the attempt. I'm trying to find the apparent instantenous "r" of an object moving along an ununiform slope where "r" is the radius of a...

If no one here can help me solve it, can this thread be moved back to Classical Physics where I posted it?

Dan, the axes of rotation are not at right angles to each other. The circle is free to rotate around its center and the fixed point at the end of the rod a distance "l" from the center of the circle. The rocket will also at times be slowing down the system as the periods about each axes of...

I realize it's mechanics, but does this really belong in introductory physics?

A 2 dimensional circle of radius "r" and mass "m" is attached through the center of the circle by a rigid, massless rod to a fixed point of rotation a distance "l" away. A massless rocket is attached to the outside of the circle a height of 0 away from the circle's surface and "r" away from the...
