1.(a)A centrifuge accelerates from rest with an angular acceleration of 30rad/s^2.What is the angular velocity of the centrifuge after 30s?(b)The angular velocity of an auto mobile engine accelerates from 800rpm to 3000rpm in 15s.calaculate the engines angular acceleration.

Angualar velocity final=intial w + angular acceleration* time

In the second part, change rpm to radians/sec^2
