Physics
Imagine two concentric cylinders, centered on the vertical z axis, with radii r t e, where e is very small. a small frictionless puck of thickness 2e is inserted between the two cylinders, so that it can be considered a point mass that can move freely at a fixed distance from the vertical axis. if we use cylindrical polar coordinates (p,p, z) for its position then p is fixed at p r. while and z can vary at will. write down and solve newton's second law for the general motion of the puck, including the effects of gravity. describe the puck's motion
