A soccer ball of mass 0.30 kg is rolling with velocity 0, 0, 3.0 m/s, when you kick it. Your kick delivers an impulse of magnitude 1.6 N · s in the −x direction. The net force on the rolling ball, due to the air and the grass, is 0.28 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s after you kick it, assuming that the ball is at the origin at the moment it is kicked. Use the approximation vavg ≈ pf /m. (Express your answer in vector form.)
