Ah, now I see, thank you very much for you help. Should be able to figure it out now :smile: Edit: Yep, that did it. Again, thanks.

I realize that the the x in a) and the x in b) are different values, but I did think that the different amount of work needed to be done by the spring would be equal to mgh. Where h is the extra height. I might have been confusing by using x in equation a), then in be referring to it, but with...

Hi, hope you can help me with finding out what I am doing wrong on this problem. It goes as follows: A massless, vertical spring of force konstant k is attached at the bottom to a platform of mass mp, and at the top to a massless cup. The platform rests on a scale. A ball of mass mb is...
