A stretch spring has an elastic potential energy of 35 J when it is stretched 0.54m. What is the spring constant of the spring?

240.1 N/m

Explanation:

Applying the formula for the potential energy stored in a stretched spring,

E = 1/2ke² Equation 1

Where E = potential energy, k = spring constant, e = extension.

make k the subject of the equation,

k = 2E/e² Equation 2

Given: E = 35 J, e = 0.54 m

Substitute into equation 2

k = 2(35)/0.54²

k = 70/0.2916

k = 240.1 N/m.

Hence the spring constant of the spring is 240.1 N/m

tbh i dont know ether

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
