Question

A force of 800N stretches a certain spring a distance of 0.100m .What is its potential energy when it is compressed a distance of 7.00cm ?

Answer 1

Well all you have to do is add or multiply.

Answer 2

I expect that this spring obeys Hooke's law: Fs =-kx. So you can use the first values to find the spring constant k.

Then use the expression for spring energy Es = 1/2 k (x^2)

Answer 3
