1. A uniform, solid disk is acted on by a tangential force F, as shown. The disk is free to rotate about its central axis without friction. The mass of the disk is 4.0 kg, its radius is 0.40 m, and the force is 0.16 N.
The disk begins at rest.
(a) What are the first three quantities you could calculate?
(b) What is the moment of inertia of the disk about its central axis?
(c) What is the net torque on the disk? (1 pt)
(d) What is the angular acceleration of the disk?
(e) What is the angular frequency of the disk 3.0 s after it started?
(f) Through how many radians has the disk turned 3.0 s after it started?
(g) How many rotations has the disk made 3.0 seconds after it started?
(h) What is the tangential acceleration of a point on the edge of the disk
(i) What is the tangential speed of a point on the edge of the disk 3.0 s after it started?
(j) What is the frequency of the disk 3.0 s after it started?
(k) What is the period of the disk 3.0 s after it started?
