A soccer ball of mass 0.31 kg is rolling with velocity <0, 0, 2.1> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.7 N·s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.37 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 v avg= pf/m. (Express your answer in vector form.)

I know rf y =0, I need to find rf x and rf z
