m/s,when you kick it. Your kick delivers an impulse of magnitude1.4N·sin the−xdirection.The net force on the rolling ball, due to the air and the grass, is0.21Nin the direction opposite to the direction of the ball’s momentum. Using a time step of0.5 s,find the position of the ball at a time1.5 safter you kick it, assuming that the ball is at the origin at the moment it is kicked. Use the approximationvavg≈pf/m.
