ANSWER:Solution 32E Step 1 of 7: For a spring with force constant(k), the force for stretching or compressing the spring by x meters is given by F= kx…………..1 Where k is force constant and x is the stretching distance. Similarly for the same spring, the work done in stretching or compressing spring from x 1o x i2 given by, W= k2x ) 2 k(x 2 ……1..1
