A large centrifuge is used to expose aspiring astronauts to accelerations similar to those experienced in rocket launches and atmospheric reentries.
(a) At what angular velocity is the centripetal acceleration 10 gs if the rider is 14.0 m from the center of rotation? rad/s
(b) The rider's cage hangs on a pivot at the end of the arm, allowing it to swing outward during rotation ?
(b). At what angle ? below the horizontal will the cage hang when the centripetal acceleration is 10 gs? (Hint: The arm supplies centripetal force and supports the weight of the cage. Draw a free body diagram of the forces to see what the angle ? should be.)
