If a loop of chain is spun at high speed it can roll along the ground like a circular hoop without collapsing Consider a chain of uniform linear mass density u whose center of mass travels to the right at a high speed v If the loop rolls over a bump the resulting deformation of the chain causes two transverse pulses to propagate along the chain one moving clockwise and one moving counterclockwise A The tension in the chain in terms of u and v is uv B The speed of the pulses traveling relative to the chain is 2v C The speed of the pulses traveling relative to the chain is v D Angle each pulse travels during the time interval over which the loop makes one revolution is 2
