I have the following homework problem:
"A 200-g mass attached to the end of a spring causes it to stretch 5.0 cm. If another 200-gmass is added to the spring, the potential energy of the spring will be"
I know the answer is 4 times as much but I am not quite sure how the answer is being reached.
I thought I could use the forumla:
U= 1/2 kx^2
But I am wrong.
Any help would be much appreciated!
Thank you!
