Please show your work. Thank you! 71. A space station consists of two donut-shaped living chambers, A and B, that have the radii shown in the figure. As the station rotates, an astronaut in chamber A is moved 424 m along a circular arc. How far along a circular arc is an astronaut in chamber B moved during the same time if r_a = 132 m and r_b = 403 m? Note: Express your answer in whole numbers. No unit is required for the final answer.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
