Four balls, each of mass m, are connected by four identical relaxed springs with spring constant k. The balls are simulataneously given equal initial speeds v directed away from the center of symmetry of the system.
A puck of mass m = 1.00 kg slides in a circle of radius r = 23.0 cm on a frictionless table while attached to a hanging cylinder of mass M = 3.80 kg by a cord through a hole in the table. What speed (in m/s) keeps the cylinder at rest?
