Homework Help: Momentum of biker dragging foot

  1. Jul 11, 2005 #1
    A 77.0 kg rider sitting on a 6.6 kg bike is riding along at 8.1 m/s in the positive direction. The rider drags a foot on the ground and slows down to 4.0 m/s still in the positive direction. What is the change in momentum of the rider and bike?
