Question:
Racing disk Figure shows two disk that can rotate about there centers like a merry-go-round. At time t = 0, the references lines of the two disks have the same orientation. Disk A is already rotating, with a constant velocity of 9.5 rad/s. Disk B has been stationary but now begins to rotate at a constant angular acceleration of 2.2 rad/s2.
(a) At what time t will the reference lines of the two disks momentarily have the same angular displacement θ?
(b) Will that time t be the first time since t = 0 that the reference lines are momentarily aligned?
