06. Famous quarterback Fleet O. Foote is attempting a quarterback draw by running up the middle toward his goal line at 15 ft/s (4.6 m/s). A line backer hits him squarely, and the Zombined final velocity is 12 ft/s (3.7 m/s) at an angle of +120. from the quarterback's original direc tion. The time it took to change direction at impact was 0.20 s. Choose an appropriate horizontal coordinate system and calculate the average acceleration vector of the quarterback during the tackle.
