###### Question:

11. +-/2 points OSColPhys1 6.3.029. My Notes Ask Your Teacher A large centrifuge, like the one shown in Figure 8.30, is used to expose aspiring astronauts to accelerations similar to those experienced in rocket launches and atmospheric reentries. Free body diagram F = net F 16, Figure 8.30 (a) At what angular velocity is the centripetal acceleration 10 gs if the rider is 16.0 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 as shown in Figure 8.30(b). At what angle e 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.)
