3. When a certain spring is expanded 10cm from its natural position and held fixed, the force necessary to hold it is 4.5 x 106 dynes. Find the work W required to stretch the spring an additional 15 centimeters. Be sure to draw a picture of the setup. 1 Furthermore, calculate the work done in stretching the spring from 15cm to 25cm beyond it's natural length. Would you expect to do more work when stretching the spring 10cm more when it is already stretch to 15cm beyond it's natural length, versus just stretching the spring 15cm from it's natural lenght?
