question 8

Short Answer

A 3.45-kg centrifuge takes 100 s to spin up from rest to its final angular speed with constant angular acceleration.A point located 8.00 cm from the axis of rotation of the centrifuge moves with a speed of 150 m/s when the centrifuge is at full speed.
(a)What is the angular acceleration (in rad/s²)of the centrifuge as it spins up?
(b)How many revolutions does the centrifuge make as it goes from rest to its final angular speed?
