A centrifuge in a medical laboratory rotates at an angular speed of 3500 rev/ min. When switched off, it rotates through 41.0 revolutions before coming to rest. (a) Find the angular speed in rad/s. (b) Find the displacement in radians. (c) Find the constant angular acceleration of the centrifuge.

a. Do that, 1rev=2PI radians, 1min=60sec
b.
displaement=2PI*revolutions
c. Wf^2=Wi^2+2 a d find a.
