A light spring has an unstressed length l. It is described by Hooke's law with spring constant k. One end of the horizontal spring is attached to a vertical axle, and the other end is attached to a puck of mass m that can move without friction over a horizontal surface. The puck is set into uniform circlular motion with period 7.
(i) Firstly, derive the equation for the extension of the spring.
(ii) Thus, determine the mass of the puck beyond which the spring cannot constrain the circular motion.

One end of a spring with a force constant of k 10.0 N/m is attached to the end of a long horizontal frictionless track and the other end is attached to a mass m = 2.20 kg which glides along the track. After you establish the equilibrium position of the mass-spring system, you move the mass in the negative direction (to the left), compressing the spring 1.73 m. You then release the mass from rest and start your stopwatch, that...
