Figure gives angular speed versus time for a thin rod that rotates around one end. The scale
Question:
Figure gives angular speed versus time for a thin rod that rotates around one end. The scale on the w axis is set by wy = 6.0 rad/s.
(a) What is the magnitude of the rod's angular acceleration?
(b) At r = 4.0 s, the rod has a rotational kinetic energy of 1.60 J. What is its kinetic energy at t = 0?
o (rad/s) ti(s) 4 5 6

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.
