When a spring is stretched by 1.00 m, its spring potential energy is 20 J. What is the spring constant, in N/m? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
