Hi Guys, I am currently a sophomore and I am having some trouble choosing between IB Physics, IB Chemistry, and IB Biology. I can select two of these courses for next year but I can't seem to make a decision. All of them will be helpful for the fields I am thinking of going into, and they all...

Homework Statement Hey guys, i have a kind of unusual question. My physics class does something called standards based grading where we have to isolate specific physics skills and practice them, and then we are tested on them. Does anyone know where i can find practice questions about Newton's...

Ok, i think i got the right answer. Ee= 1/2 (625)(0.0078)^2 Ee= 1/2(625)(0.00006) Ee= 0.01875J Thank for all the help!

I divided 12.5 by 20 and got 0.625, but should i have converted before dividing?

For part A, it had a diagram and the displacement was 20 cm and the force was 12.5N so i calculated 20*12.5/2= 125J

Homework Statement Hey guys, I'm having some trouble finding the exact quantity of energy storied in this spring problem. It's like a problem with parts A and B, part A says "Determine the amount of work required to stretch the spring from 0 to 20 cm. I found that to be 125J. For Part B, it...
