A spring has a force constant of 12.9 N/m and a rest length of 0.25 m. Some amount of work is expended to stretch the spring to a length of 0.40 m. How much more work is required to stretch the spring to a length of 0.65 m?

Step 1

The work done expended to stretch the spring is

Step 2

Substitute the values to find the work done to stretch the spring from 0.25 m to 0.40 m.

Step 3

Substitute the values to find the work done to s...
