3) A 10dm diameter pulley of moment of inertia 8.00x10 kg m2 has weights attached by strings to it on either side and one exerts a force of-10.0 N k on it at a position -8 cm i and the other exerts a force of -20.0 N k on it at a position +8 cm i. The pulley was initially at rest and these torques and no others act on it for 200 milliseconds. What is the angular velocity of the pulley at the end of the 200 milliseconds? What is the rotational kinetic energy of the pulley in (3) at the end of the 200 milliseconds?

A pulley having a rotational inertia of 1.2 ✕ 10-3 kg·m^2 about its axle and a radius of 25 cm is acted on by a force, applied tangentially at its rim, that varies in time as F = 0.50t + 0.30t^2, where F is in newtons and t in seconds. If the pulley was initially at rest, find its angular speed after 10.0 s. ANSWER in rad/s^2
