Discs Or Drums?

For a bit of fun Energy is Kinetic energy KE = (M*V*V)/2 (can't figure how to get squared!).

So a Sierra at 1000 Kg doing 50 mph, must change to metres per sec. errr. 22.35 mps

KE is 249761.25 Joules

A 500 Kg car at 100 mph is 499522.5 Joules

So our little car at 100 compared to a Sierra at 50 has twice the energy because of the square, but half the energy of the Sierra at 100 mph.

Errr yeah, I think . I threw the question out to see what would come back but I have a sneaky suspicion that your sums are better than mine. I shall be erring on the side of caution and using discs all round, probably with a servo .
