13. CHALK Two people start at the same place and walk around a circular lake in opposite directions. One walks with an angular speed of 1.7 x 10-3 rad/s, while the other has an angular speed of 3.4 x 10-3 rad/s. How long will it be before they meet? 14. A space station consists of two donut-shaped living chambers, A and B, that have the radii shown in the drawing. As the station rotates, an astronaut in chamber A is moved 2.40 x 102 m along a circular arc. How far along a circular are is an astronaut in chamber B moved during the same time? A = 3.20 x 102 m
