A disc rotates about a fixed axis. Its angular velocity ω varies with time according to the equation ω=at + b. Initially at t = 0 its angular velocity is 1.0 rad/s and angular position is 2 rad; at the instant t= 2s angular velocity is 5.0 rad/s. Determine angular position θ and angular acceleration when t = 4s.
