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.

- Two blocks, A and B (with mass 45 kg and 120 kg, respectively), are connected by a string, as shown in the figure below. The pulley is frictionless and of negligible mass.

In mountainous regions, highways sometimes include a runaway truck ramp, and you are asked to help with the design of such a ramp. A runaway truck ramp is often a lane of gravel adjacent to a long downhill section of roadway where trucks with failing brakes may need assistance to stop. Working with your supervisor, you develop a worst-case scenario: a truck with a mass of 6.00 × 104 kg enters a runaway truck lane traveling at 34.1 m/s. Assume that the maximum constant value for safe acceleration of the truck is -5.00 m/s². Any higher magnitude of acceleration increases the likelihood that semi-trailer rigs could jackknife. Your supervisor asks you to advise her on the required length (in m) of a runaway truck lane on a flat section of ground next to the roadway. marrow_forwardA large cruise ship of mass 6.20 × 107 kg has a speed of 10.2 m/s at some instant.
