A student hangs a 0.12$ kg object on a spring. sets it into oscillation. and obtains the data for the position and velocity of the object as a function of tune shown in the graphs below.

Next the student is given a rubber hand and asked to determine whether the relationship between the restoring force exerted by the rubber hand and the amount it is stretched is the same as that of an ideal spring.

(a) Describe an experimental procedure that the student could use to coned the necessary data, including all the equipment the student would need.

(b) Dow should the student analyze the data to determine whether the relationship between the restoring force exerted by the rubber hand and the amount it is stretched is the same as that of an ideal spring? What evidence from the ,analysis would be used to make the determination?
