(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A space station consists of two doughnut 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 10^{2}m along a circular arc. How far along a circular arc is an astronaut in chamber B moved during the same time?

here is the picture for more reference:

2. Relevant equations

i dont know if these will help we just got alot today so here:

w=[tex]\theta[/tex]/Delta t

*v=v_{o}+at ~ w=w_{o}+[tex]\omega[/tex]t

*v^{2}=v_{o}^{2}+2ax ~ w^{2}=w_{o}^{2}+2[tex]\omega[/tex][tex]\theta[/tex]

*x=v_{o}t+(1/2)at^{2}~ [tex]\theta[/tex]=w_{o}t+(1/2)at^{2}

the ones with * means i changed it to what the problem is about. means the same thing just different letters so you wont get confused i guess.

3. The attempt at a solution

i have no idea what im supposed to do. i know the arc length should be the same as the radius because its has something to do with radians? i have no clue what im supposed to do. please help me.

thank you!
