Compute the work required to stretch a spring from 9 to 13 cm past equilibrium, assuming that the spring constant is 𝑘=140 kg/s2.

Answer 1

Ej N.,

What is the issue here? Integrate the force (displacement * spring constant) over the range of motion, taking care to convert to standard units. By the way, how much pull would there be at each of the endpoints? Express in units you can understand, such as "lbs gravitationally".
