The length L in feet that a spring is stretched from it's natural length by work W in foot-pounds is given by the formula L=v2w÷k,

Question

where K is a constant for the given spring. If a certain spring has a constant of 23.8, and the spring is to be stretched 1.2 feet from it's natural length, how much work will be necessary?

Answer 1

w = work

L = length

k = constant

 

Given:

L = 1.2 ft

k = 23.8

 

 

Plug in the values into the formula to find the work.
