A 10.-newton force is required to hold a
stretched spring 0.20 meter from its rest position. What is the potential energy stored in the
stretched spring?

    I believe the answer is 1/2kx^2=Fd=10N(0.2m)=2J. Hopefully someone checks this.

    It's actually 1J. You forgot to divide by one! Thank you!

    Double check that. Are you sure that it is 1J?

    It's definitly 1J
