A point on the edge of a disk rotates around the center of the disk with an initial angular velocity of $3\,\text{rad/s}$ clockwise. The graph shows the point’s angular acceleration as a function of time. The positive direction is considered to be counterclockwise. All frictional forces are considered to be negligible. The angular acceleration stays at the value shown on the graph after $2.0\,\text{s}$. What is the angular displacement of the point from $t = 0$ to $t = 10\,\text{s}$?
