A disk with a radial line painted on it is mounted on an axle perpendicular to it and running through its center. It is initially at rest, with the line at ?0 = -90
A disk with a radial line painted on it is mounted on an axle perpendicular to it and running through its center. It is initially at rest, with the line at ?0 = -90 degree . The disk then undergoes constant angular acceleration. After accelerating for 3.1 s, the reference line has been moved part way around the circle (in a counterclockwise direction) to ?f = 130 degree . Given this information, what is the angular speed of the disk after it has traveled one complete revolution (when it returns to its original position at -90 degree )?Explanation / Answer
The applicable kinematic eqn for this situation is:
? = ?o + ?ot +
