A pulley, with a rotational inertia of 2.4 x 10-2 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 = 0.60t +0.30t2, with F in newtons and t in seconds. The pulley is initially at rest. At t = 4.9 s what are (a) its angular acceleration and (b) its angular speed? (a) Number: 46.49 Units rad/s^2 (b) Number + 86.937 Units rad/s E |||
