- An engine flywheel initially rotates counterclockwise at 6.25 rotations/s. Then, during 20.3 s, its rotation rate changes to 3.83 rotations/s clockwise. Find the flywheel's average angular acceleration (including its sign) in radians per second squared. Define counterclockwise rotation as positive.A centrifuge in a medical laboratory rotates at an angular speed of 3,550 rev/min. When switched off, it rotates through 54.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.How fast (in rpm) must a centrifuge rotate if a particle 7.5 cm from the axis of rotation is to experience an acceleration of 2.0×105 g's? Express your answer using two significant figures.
