If i wasn't willing to be learning, I wouldn't be on this site and signed up. And he was being rude in my opinion. I'm on here to try and figure out this homework question. I have to answer it and if I didn't care about it, I would make the answer up. But I am confused and on here seeking...

listen, i appreciate your help but you don't have to be rude about it. i;m not a mathematician and I have no interest in physics. You have to understand how confusing reading this forum is when you are confused from the start. Formulas are being tossed around left and right so I do not know...

i have everything up to the velocity! Help!

is the total energy 3.375 correct? I did Total energy = 1/2kA^2 E = 1/2 (300N)(0.15cm)^2 E=3.375 J

So far I have U = 1/2 kx ^2 U= ½(300)(.10)^2 1.5 J and that is IT! I have no idea what to do next or even what I'm doing for that matter. I know KE= ½(mv^2) but i don't have the velocity yet. oyyyy

I am also working on this question. The PE is 1.5 J or 15 J? From there, how would we find the KE? I am very confused! Too many numbers!
