Question #1040

Hi, I have re arranged V2 = √2 (p1-p2)/p(1-(a2/a1)^2) to get p1-p2 and got p1-p2 = (v2^2/2 )*1000(1-(a2/a1)^2). I would like to know if that is correct. I am not the best at formulae transposition. (if it cant be seen on the screen, everything after V2= if the first part is under a square root) Thanks
