A disk with r=1m rotates at 200 rpm, it takes 15 s for brakes to make the disk come to a half. a) what is the angular velocity? b) what is the alpha angular acceleration of the disk during the 15-second time frame? c) what is the tangential velocity after 10 seconds in the brake time period?

Im a disk with r= Im rotates at 200rpm, it takes 155= for brakes to make the disk come to (a) what is the a halt. angular Veloving 660 (b) what is a (alpha) angular acceleration of the disk during the 15 second time frame. (C) what is the tangential Velocity after 10 seconds ins brake time period. W-o/xfd_d
