Rank the following cases in terms of lowest to highest angular momentum: A 15.0 kg-m2 disk spinning at 0.7 rad/s A 5.0 kg-m2 disk spinning at 3.0 rad/s A 0.8 kg-m2 disk spinning at 10.0 rad/s A 10.0 kg-m2 disk spinning at 1.0 rad/s

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
