Chapter 2.5, Problem 2.3CE
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.

(b) Relative to the freight car, is the ball moving faster or slower when the train is moving than when the train is standing still?
A “moving sidewalk” in an airport terminal moves at 1.0 m/s and is 35.0 m long. If a woman steps on at one end and walks at 1.5 m/s relative to the moving sidewalk, how much time does it take her to reach the opposite end if she walks (a) in the same direction the sidewalk is moving? (b) In the opposite direction?

- on december 25, 2004, during a NASA mission to Saturn, the spacecraft Cassini released a probe named Huygens, which landed on the Saturnian moon titan on January 14, 2005. huygens was released from the main spacecraft at a gentle relative speed of 31 cm/s. As Huygens moved away, it rotated at a rate of 7 revolutions per minute.(a) How many revolutions had huygens completed when it was 150m from Cassini?

I'm very confused and now stuck on the questions. On the apollo 14 mission to the moon, astronaut Alan Shepard hit a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 25 m/s at an angle 26 degrees above the horizontal. A.) How long was the ball in flight? B.).How far did it travel? C.) Ignoring air resistance, how much farther would it travel on the moon than on the earth?
