I cant tell how big the loop is but lets say its about 25m and say that the average car has a mass of 1500 kg. F=Mv^2/R but the force at the top providing the centripetal force will be the weight of the car and since the masses in the equations are the same v^2/R = g. Therefore v= (square root) 9.81m/s^2*25m gr = 15.7m/s Which is about 57km/h. I think I must have missed something because that doesn't seem very fast at all :S
They need to be going 15.7m/s at the top. If we assume the cars put it in neutral at the bottom of the loop we can get a bit of an overestimate. w/ conservation of energy, 1/2 m Vtop^2+m g 2 r=1/2 m Vbottom^2, so Vtop^2+4 g r=Vbottom^2=(15.7^2+4*9.81*25) (m^2/s^2)=(35m/s)^2 [approx], so 80ish mph or 126 kph.
Lets see... at close to the bottom of the loop that would be... 6gs total. Not bad!
It's way over 25m. The car is about 14 pixels high in the picture, and the loop is about 405. So 405/14=29. And if we say the car is about 1.6m, the loop is 46m. Very roughly done, but you can kinda see by eye that it's over 25m.
