Question

A spring with a force constant of 167 N/m is compressed 1.0 cm. The work done on the spring is?

Answer 1

The work is the same as the energy you put into it to compress it (work-energy theorem) This is given by

`W= (1)/(2)k x^(2)`

We must put compression in meters, x=0.01m, and then

`W= (1)/(2)167 (N)/(m) (0.01)^(2) = 0.00835J`
