A hoop of mass M=2.0kg and radius R=0.25m rotates at 478 revolutions per minute after making 19.11 revolutions in 4.00s.

A) Assuming constant angular acceleration calculate the angular acceleration and initial angular speed of the disk

B) Sketch a graph of the angular speed vs. angular displacement during the 4.00s time interval. Make sure you identify the initial and final coordinate pairs in your plot. Please make a reasonable large graph and describe the shape of the graph so that I can understand it
