What was the energy of the spring if it did 4 J work?
| May 11, 2021 | education
By definition, work A = – (W2-W1), where W1 and W2 are the initial and final energies, respectively. Since the spring has overcome, that is, has done a certain job, then:
W2-W1 = A
W1 = A-W2
Due to the fact that the problem does not indicate the final energy W1, it is not possible to find W2.
