Brazilian soccer star Marta has a penalty kick in the quarter-final match. She kicks the soccer ball from ground level with the (x, y)-coordinates (81, 19) on the soccer field shown in the figure and with initial velocity vo = 8i – 4j + 31k ft/s. Assume an acceleration of 32 ft/s? due to gravity and that the goal net has a height of 8 ft and a total width of 24 ft. 105 ft [12 | 12 105 ft 165 ft 165 ft Determine the position function that gives the position of the ball t seconds after it is hit. (Use symbolic notation and fractions where needed.) r(t) = r;(t)i + r;(t)j + rk (t)k
