Chapter 2, Problem 12QQ
Choose the best answer to each of the following. Explain your reasoning.
Which of the following best describes why the Greeks rejected the correct explanation for apparent retrograde motion? (a) They did not realize that planets sometimes appear to move backward relative to the constellations. (b) They predict that if Earth orbited the Sun, then stellar parallax should occur, but they could not detect this parallax. (c) They never even considered the possibility that Earth could orbit the Sun.

He plans to use a uniform elastic cord, tied to a harness around his body, to stop his fall at a point 6.00 m above the water. Model his body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test he finds that when hanging at rest from a 5.00 m length of the cord, his body weight stretches it by 1.55 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the bridge.
