Max plays middle linebacker for South's football team. During one play in last Friday night's game against
New Greer Academy, he 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° counterclockwise from east (30° W of S) before finally knocking the wind out of New Greer's wide receiver. Determine
the magnitude and direction of Max's overall displacement.
