Topic: Rotational Motion Plate #18. After using your DVD player to watch a movie, you pressed Rotation the stop button and the disc started to slow down. Initially the disc is rotating at 40 rad/s and then slows down at a constant rate of 12rad /s². At the same time, line AB on the disc is at the x-axis as shown in the figure. A. What is the angular velocity of the disc at t = 0.6 s? B. Find the angle that line AB makes with the x-axis at the given time.

The figure below shows two disks that can rotate about their centers like a merry-go-round. At the time t = 0, the reference lines of the two disks have the same orientation. Disk A is already rotating, with a constant angular velocity of 8.9 rad/s. Disk B has been stationary but begins to rotate at a constant angular acceleration of 2.35 rad/s?. Disk A Disk B (a) At what time t will the reference lines of the two disks momentarily have the same angular displacement 0? rad
You have a horizontal grindstone (a disk) that is 88 kg, has a 0.31 m radius, is turning at 89 rpm (in the positive direction), and you press a steel axe against the edge with a force of 17 N in the radial direction. Assuming that the kinetic coefficient of friction between steel and stone is 0.20, calculate the angular acceleration of the grindstone in rad/s2. What is the number of turns, N, that the stone will make before coming to rest?
