A light spring has unstressed length of 15.1 cm. It is described by Hooke's law with spring constant 4.39 N/m. One end of the horizontal spring is held on a fixed 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 motion in a circle with a period of 1.38 s. a. Find and expression for the extension of the spring x as it depends on m.
b. Evaluate x for m = 0.075 kg
c. Evaluate x for m = 0.150 kg
d. Evaluate x for m = 0.225 kg.
e. Describe the pattern of variation of x as it depends on m.
