(10%) Problem 1: At its lowest setting a centrifuge rotates with an angular speed of w] = 350 rad/s. When it is switched to the next higher setting it takes I = 14 s to uniformly accelerate to its nal angular speed (02 = 550 rad/s. E & 50% Part (:1) Calculate the angular acceleration of the centrifuge al in rad/s2 over the time interval t. D 3 50% Part (b) Calculate the total angular displacement (in radians) of the centrifuge, A0, as it accelerates from the initial to the nal speed. Grade Summary A0 = l Deductions 0% Potential 100%
