If a child of 50kg is riding a bike at 10ms-1, and suddenly stops pedaling, obviously they will eventually come to a halt due to friction and air resistance. I was just wondering what happened to their momentum. It decreases from 500kgms-1 to zero, where does it go? (Similarily for any object that gradually comes to a halt due to friction/resistance).
