I believe it is initial gpe (distance x) = gained ke + gained epe (extension as x-26).(Original post by shazzy1230)
Does anyone know how to derive the energy equation in question 8? I can't seem to get it
I dont have the paper on me rn, but i can remember that, it should drop out from there. Is this the q where x > 26?
Is freshers still worth it?
