# a disc rotates about a fixed axis. Its angular velocity w varies with time according to the equation w=at+b. Initialy at t=0 its angular velocity is 1 rad/s and and angular position is 2rad , at the instant t=2s , angular velocity is 5 rad/s . Determine angular positon and angular accelaration a when t =4s

Dear student,
