1. The problem statement, all variables and given/known data As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration. Specifically, the astronaut is fastened securely at the end of a mechanical arm that then turns at constant speed in a horizontal circle. Determine the rotation rate, in revolutions per second, required to give an astronaut a centripetal acceleration of 2.89g while in circular motion with radius 9.46 m. 2. Relevant equations radial(centripetal) acceleration= v^(2) / r v= 2(pi)(r) / T 3. The attempt at a solution radial acc.= (9.8)(2.89)= 28.322 m/s^(s) 28.322 m/s^(2) = v^(2) / 9.46m v= 16.368 T= 2(pi)(9.46m) / (16.368) = 3.631 Is that right???
