The acceleration a versus spring length L observed when a 0.5-kg mass is pulled along a frictionless table by a single spring is shown in the following table:

(a) Make a plot of the force exerted by the spring versus length L.

(b) If the spring is extended to 12.5 cm, what force does it exert?

(c) How much does the spring extend when the mass is suspended from it at rest near sea level, where g = 9.81 N/kg?
