A large centrifuge, like the one shown in figure (a), is used to expose aspiring astronauts to accelerations similar to those experienced in rocket launches and atmospheric reentries. ac = 8.25 g d = 17.5 m At what angular velocity is the centripetal acceleration 8.25 g if the rider is 17.5 m from the center of rotation? Give your answer in rad/s. ω = The rider’s cage hangs on a pivot at the end of the arm, allowing it to swing outward during rotation as shown in figure (b). At what angle θ below the horizontal will the cage hang when the centripetal acceleration is 8.25 g? Give your answer in degrees.
