11. Astronauts are on a spacecraft traveling at 2.7 x 108 m/s with respect to Earth. (a) Calculate ẞ and y for the relative motion of Earth and the spacecraft. (b) According to a biology text, it takes 45 s for blood to circulate around the human body. If astronauts on the spacecraft run experiments to determine how long (on their own clocks) it takes their blood to circulate around their bodies. What should they measure? Even if you aren't sure about a numerical answer to this question, you should at least be able to explain whether the time will be the same, shorter, or longer than 45s. (c) If Earth-bound scientists use remote equipment to measure how long it takes for the blood to circulate around the astronaut's bodies, how long will will it take according to clocks on Earth? Even if you aren't sure about a numerical answer to this question, you should at least be able to explain whether the time will be the same, shorter, or longer than 45 s.

CASE STUDY On planet Betatron, mass is measured in bloobits and length in bots. You are the Earth representative on the interplanetary commission for unit conversions and find that 1 kg = 0.23 bloobits and 1 m = 1.41 bots. Express the density of a raisin (2 103 kg/m3) in Betatron units.
A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69
