@trinsec Not double momentum there is a friction from the road, air and impact point..
What doesn't make sense to me is how it gets launched considering that both are haing a "forward" velocity so i would expect the wheel to just bounce off the car instead of the wheel gripping and throwing the car in the air like a catapult
@trinsec also then going back and hitting the car again :D the wheel had to change the velocity while under the car and then get launched backwards in a way that made it spin forward to hit again..
@kreyren It's perfectly possible. The wheel that got loose is still having its momentum, and if the other car is faster and end up onto the wheel, it gets launched because of the direction of the loose wheel. Double momentum basically, and then it's going to the moon.
