A puck of mass 4 kg is attached to a spring of force constant 100 N/m and natural length 0.07 meters. The other end of the spring is attached to a fixed pivot. The puck is set into circular motion so that the spring is stretched 0.03 meters from its natural length as the puck circles.
(a) What is the centripetal force acting on the puck?
(b) How much work is done by the puck in one full circle?
