During the time a compact disc (CD) accelerates from rest to a constant rotational speed of @ = 38 rad/s, it rotates through an angular displacement of 0 = 11.5 radians. What is the angular acceleration, o, (in rad/s ) of the CD? Please round your answer to the nearest whole number (integer).Consider three particles A, B, and C that are rotating about a vertical axis. The masses of these particles are: mA = 4mo, me =6mo and mc = 5mo. Their perpendicular distances from the axis are: TA = 200, IB = 6ro, and re = 5ro. Rank the three particles according to their moments of inertia, largest to smallest
