Asoccer ball of mass 0.35 kg is rolling with velocity 0, 0, 1.8 m/s, when you kick it. your kick delivers an impulse of magnitude 1.8 n · s in the −x direction. the net force on the rolling ball, due to the air and the grass, is 0.26 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.)
