Spinning Disk 8-0 A disk is mounted on an axle perpendicular to it and running through its center. It has a radial line painted on it. The disk is initially at rest, with the line at 00=-90. 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 0117. a) What was the angular acceleration of the disk? a=> rad/s2 Help Reset Enter HELP: This is a rotational kinematics problem with constant angular acceleration. What equation relates angle, time, and angular acceleration? b) What is its angular speed as the line passes through 117? 00 rad/s Help Enter
