Alright, what formulas do you know applies to this situation?

albert0898 · Answer

F = kx I think

nottim · Answer

Alright, compare the unstretched spring to an unstretched spring. Do this, by applying the formula twice, but separately. do you understand?

nottim · Answer

F=kx (original), and 2F=kx (stretched). Solve for x, in both situations.

albert0898 · Answer

F/k = x

and

2F/k = x
