[填空题]
A centrifuge in a medical ln,t ; je(bf 7w*e7bmvfaboratory rotates at a ro mzg n g6ye5,o:8fdr,xtational speed of 3600 rev/min. When switched off, it r5m onfx ,6dr g,zge:y8otates 50.0 times at a constant angular acceleration before coming to rest.
(a) Determine the initial angular speed of the centrifuge.    $rad/s$
(b) Determine the angle (in radians) through which the centrifuge rotates before coming to rest.    $rad$
(c) Calculate the constant angular acceleration of the centrifuge.    $rad/s^2$
(d) Calculate the time necessary for the centrifuge to come to rest.    $s$
