Hi all. I'm doing a little program for my own fun and I'm having troubles with the physics. I need to be able to calculate where an object is on a circle after an amount of time has passed. I know the radius (R) of the circle, the starting x (Sx) and y (Sy) positions, and the velocity (v). I'd like to be able to generated the finishing x (Fx) and y (Fy) positions. The velocity and radius are constant for each object, but I have several objects rotating around a central point. It's similar to planets orbiting the sun, but I don't need to have any gravitational interaction between the objects. I also know the mass of the objects (m) if I need that for calculating. Can anyone give me a formula or set of formulas to solve for Fx,Fy? Thanks!
