Physics 172 – Recitation 03 Spring 2012 You will find more information about the new topics covered by today’s problems throughout chapter 2 of the text. Problem 1. Two astronauts decide to pass some time during a long stay aboard the ISS (International Space Station) by making a video entitled Toys in Space . They record the behavior of toy-like systems as they rotate, vibrate and move through the station. One “toy” whose motion they record consists of a pair of metal spheres whose centers are connected by a weak spring. The spring’s relaxed length is l 0 = 10 cm. Its stiffness is k = 20 N/m, and its mass is very small compared to the masses of the spheres, m 1 = 0.1 kg and m 2 = 0.2 kg. Assume that the spheres are small compared to the distance between their centers. The astronauts record one motion of this toy that begins with the sphere centers at initial locations r 1 =< 2.10,0.02,1.30 m and r 2 =< 2.05, - 0.02,1.34 m with initial velocities v 1 =< - 0.07,0.05,0.12 m/s and v 2 =< - 0.08,0.04,0.13 m/s in a coordinate system whose origin is near the center of the ISS lab space. a)
