Question:
Starting from rest, a disk rotates about its central axis with constant angular acceleration. In 5.0 s, it rotates 25 rad. During that time, what are the magnitudes of
(a) The angular acceleration and
(b) The average angular velocity?
(c) What is the instantaneous angular velocity of the disk at the end of the 5.0 s?
(d) With the angular acceleration unchanged, through what additional angle will the disk turn during the next 5.0 s?
Step by Step Answer:
We assume the sense of rotation is positive which since i...View the full answer

Angular movements are produced when the angle between the bones of joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. The extension is the opposite of flexion in that the angle between the bones of a joint increase.
