A centrifuge in a medical laboratory rotates at an angular speed of 3600 rev/min A) what is the centripetal force acting on a red blood cell (mass m = 3.0 x 10^-16 kg) Which is at a distance r = 15 cm from the axis of rotation? B) when the centrifuge is switched off, it rotates through 50 revolutions before coming to rest. Find the constant angular acceleration of the centrifuge.
