A pulley with a rotational inertia of 11 x 10-3 kgmiddotm2

A pulley, with a rotational inertia of 1.1 x 10-3 kg·m2 about its axle and a radius of 5.8 cm, is acted on by a force applied tangentially at its rim. The force magnitude varies in time as F = 0.16t + 0.43t2, with F in newtons and t in seconds. The pulley is initially at rest. At t = 2.1 s what are (a) its angular acceleration and (b) its angular speed?
