A physicist viewing a scene from the interior of the spacecraft notices that the diameter of the rotating portion of the ship is about five times the height of an astronaut walking in that section (or about 10m). Later, in a scene showing the spacecraft from the exterior, she notices that the livign quarters of the ship rotate with a period of about 30s. Compare the centripetal acceleration of a 1.6-m-tall astronaut at his feet to that at his head. a feet / g = ?? a head / g = ??

Explanation / Answer

R=10/2=5m

A/a = (R/(R - 1.6)) = 5/3.4;

so A = a 1.470588235 = 1.47a.

The acceleration at the feet is 1.47 the acceleration at the head.
