I believe that the common drag equation is this: Fdrag= 1/2*rho*velocity^2*Cross section*Constant D=1/2rv^2*s*c Please correct me if this is wrong. Anyway, I was wondering, what if the drag exceeded the velocity?? the Object would rebound, but certaintly this is not possible. what if density was .2,s and c were 1? then it would be v^2*.1 then, what if velocity was 20? 400*.1=40. Can somthing rebound with twice the speed? I think not. My equation must be wrong.
