Energy

A 3.2 kg block is hanging stationary from the end of a vertical spring that is attached to the ceiling. The elastic potential energy of this spring/mass sytem is 1.4 J. What is the elastic potential energy of the system when the 3.2 kg block is replaced by a 5.7 kg block?

5.7 / 3.2

Then multiply the answer to that by 1.4

That will give you the answer, if the relationship is simply linear and based on just that one quantity.

If that's not the case, and I'm just making a random assumption, then what I said above is wrong.
