5. A drum rotates around its central axis at an angular velocity of 12.6 rad/s. drum slows down at a constant rate to 8.4 rad/s in 2 seconds, a) What is the angular acceleration? b) Through what angle O did it rotate? the 6. You roll a disk along the sidewalk. The disk's mass is 0.5kg, r=0.12m, v=2m/s. Find the total Kinetic Energy. That is the combined energy of translation and rotation. Remember the Moment of Inertia of a disk.
