In a 1997 soccer match between Brazil and France, Roberto Carlos scored a free kick from 35 m out. He was one-third of the length of the field away from the goal, with the four-person "wall" directly in front of him. A ball boy 30 ft away from the goal ducked, as he thought the ball was heading his way at 80 mph. Consider the spin on the ball to be 9 rps. Take density of air to be 1.2 kg/m3. The radius of the football is 0.111 m and its mass is 0.425 kg. Calculate the deflection Carlos achieves after the ball travels 35 m forward. Ignore drag. Round the final answer to the nearest whole number. In a 1997 soccer match between Brazil and France, Roberto Carlos scored a free kick from 35 m out.
