This concerns a debate I'm having with two friends of mine, hope someone here can help.
You have a train traveling at 100km/h. Inside the train there is a car traveling at 100km/h. Inside the car is a jogger running at 20km/h.
Suddenly the train and car stop and the jogger is thrown forward out of the train and car. At what speed relative to an outside observer?
100? 200? 220?
(We are Computer Scientists hence our lack of understanding :) )
