It takes 90 j of work to stretch a spring 0.2 m from its equilibrium position. How muc work is needed to stretch it an additional 0.4 m?

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
