During Sunday's superbowl, the middle linebacker for the Seattle Sea Hawks made the following movements after the ball was snapped on third down. First, he back-pedaled in the southern direction for 2.6 meters. He then shuffled to his left (west) for a distance of 2.2 meters. Finally, he made a half-turn and ran downfield a distance of 4.8 meters in a direction of 240° counter-clockwise from east (30° W of S) before finally knocking the wind out of New England Patriots' wide receiver. Determine the magnitude and direction of his overall displacement.
