A pulley, with a rotational inertia of 9.4 × 10-3 kg·m2 about its axle and a radius of 6.0 cm, is acted on by a force applied tangentially at its rim. The force magnitude varies in time as F = 0.70t + 0.30t2, with F in newtons and t in seconds. The pulley is initially at rest. At t = 3.3 s what are (a) its angular acceleration and (b) its angular speed?

    Question 2 (8 marks) Applied force A vertical pulley, of radius 0.4 meter, can rotate about a horizontal axle (axle has friction) that goes through its center. The rotational inertia of the pulley about this axle is 16 x 10 kg.m. The torque due to friction in the axle is constant, with magnitude 0.8 Nm. A vertical force, of constant magnitude 11.0 N, is continuously applied tangentially to the rim of the pulley as shown above. The pulley is initially...

    A disk with a rotational inertia of 5kg*m^2 and a radius of 0.25 meters rotates on a friction-less fixed axis perpendicular to the disk and through its center. A force of 2 Newtons is applied tangentially to the rim. After five seconds this force is removed and a braking force is applied. What amount of (tangential) braking force would be necessary to slow it down to a stop in two revolutions?
