A pulley, with a rotational inertia of 1.0 x 10-3 kg-m2 about its axle and a radius
Question:
A pulley, with a rotational inertia of 1.0 x 10-3 kg-m2 about its axle and a radius of 10 cm, is acted on by a force applied tangentially at its rim. The force magnitude varies in time as F = 0.50t + 0.30t2, with F in newtons and t in seconds. The pulley is initially at rest. At t = 3.0 s what are
(a) Its angular acceleration and
(b) Its angular speed?
Step by Step Answer:
Since the force acts tangentially at r 010 m the angular acceler...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
