When different masses are suspended from a
spring, the spring stretches by different amounts as shown in the Table below.
Masses are 1.0 gram.

(a) Graph the applied force (in Newtons)
versus the stretch (in meters) of the spring, and determine the best fit
straight line. (b) Determine the spring constant (N/m) of the spring from the
slope of the best fit line, (c) If the spring is stretched by 20.0 cm, estimate
the force acting on the spring using the best fit line.
