A pulley, with a rotational inertia of 1.1 multiplied by 10^-3 kg·m² about its axle and a radius of 11 cm, is acted on by a force applied tangentially at its rim. The force magnitude varies in time as F= 0.50t + 0.30t², where F is in newtons and t in seconds. The pulley is initially at rest.

(a) At t = 6.0 s what is its angular acceleration?

(b) At t = 6.0 s what is its angular velocity?
