- A Pulley With A Rotational Inertia Of 2 4 X 10 Kg M About Its Axle And A Radius Of 11 Cm Is Acted On By A Force App 1 (41 KiB) Viewed 53 times
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?
