1. The problem statement, all variables and given/known data a space station consists of two donut shaped living chambers A and B, that have radii r(A)= 3.2x10^2m and r(B)=1.10x10^3m. As the station rotates, the astronaut in chamber A is moved 2.40x10^2 m along a circular arc. how far along a circular arc is an astronaut in chamber B moved during the same time? 2. Relevant equations 3. The attempt at a solution i used a proportion r(A)/ circular arc = r(B)/ x and solved for x i got the correct answer but my but i was wondering if there was a different way to solve this using formulas...my physics prof. would not be happy if i didnt use correct formulas. thanks!!
