1. The problem statement, all variables and given/known data A space station has a radius of 200 meters. An astronaut has a mass of 55 kilograms and the station rotates at 1.5 rev/min. What is the period of rotation for the station? 2. Relevant equations [tex]\tau[/tex]=2[tex]\pi[/tex]r/v a=v2/r Fg=mg FNET=ma 3. The attempt at a solution I think the FNET equation is Fsp=ma and I'm pretty sure you have to solve for [tex]\tau[/tex] but in order to do that I need to solve for a. How do I either find a velocity or acceleration to do this?
