A mass m slides on a frictionless ice rink. A circular wall constrains it to move inside a fixed ring of radius R (Note: gravity is irrelevant here; in the vertical direction the weight is simply opposed by a normal force from the frictionless ice.) At t = 0, the puck is moving along the inside of the ring withh velocity v0. The coefficient of friciton betweeen the puck and the wall is u Find the differential equation obeyed by...

A uniform wire of mass M and length d rotates in a horizontal plane about an axis passing through its center. Two small beads, each of mass m, are placed on the wire; friction between the beads and the wire is negligible. The beads are initially held on the wire by catches at a distance d/4 on either side of the center, and the system rotates with angular speed ω0. The catches are then released, and the beads slide outward...
