Question

A compressed spring has 16.2 J of elastic potential energy when it is compressed 0.30 m. What is the spring constant of the spring?

Answer 1

360

Step-by-step explanation:

just took the test

Answer 2

It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched. It is expressed as:

PE = W = 1/2 (kx^2)
16.2 = 1/2 (k(0.30)^2)
k = 360 J/m^2

Hope this answers the question. Have a nice day.
