9.20. Model: We will define our system to be archer arrow. + The force of the archer (A) on the arrow (a) is equal to the force of the arrow on the archer. These are internal forces within the system. The archer is standing on frictionless ice, and the normal force by ice on the system balances the weight force. Thus ext 0 F = G G on the system, and momentum is conserved. Visualize: The initial momentum i x p of the system is zero, because the archer and the arrow are at rest. The final moment
