Figure 2.11 shows the motion of various objects: Case 1. A person on a moving Ferris wheel Case 2. A person on a loop-the-loop roller coaster Case 3. The tire on a moving bicyclc Case 4. The person on the bicycle Consider the displacement of points on each object, and decide whether the object is undergoing pure translational motion and therefore may be modeled as a particle. 2.3 If the displacement of every point on the object is the same, the object is undergoing purely translational motion and may be modeled as a particle. Case 1. A person on a Ferris wheel may be modeled as a particle. Case 2. A person on a loop-the-loop roller coaster may not be modeled as a particle because the person flips upside down as he moves along the track. Case 3. The tire on a bicycle may not be modeled as a particle. Case 4. The person on a bicycle may be modeled as a particle.

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° counter-clockwise 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.
