In a large centrifuge used for training astronauts, a small chamberis fixed at the end of a rigid arm that rotates in a horizontalcircle. A trainee riding in the chamber of a centrifuge rotatingwith a constant angular speed of 2.7 rad/s experiences acentripetal acceleration of 3.1 times the acceleration due togravity.
In a second training exercise, the centrifuge speeds up from restwith a constant angular acceleration. When the centrifuge reachesan angular speed of 2.7 rad/s, the trainee experiences a totalacceleration equal to 5.3 times the acceleration due togravity.
(a)How long is the arm of the centrifuge?
(b)What is the angular acceleration of the centrifuge in the 2ndtraining exercise?
