As you finish listening to your favorite compact disc (CD), the CD in the player slows down to a stop. Assume that the CD spins down with a constant angular acceleration. A) If the CD rotates clockwise (let's take clockwise rotation as positive) at 500rpm (revolutions per minute) while the last song is playing, and then spins down to zero angular speed in 2.60s with constant angular acceleration, what is alpha_vec, the angular acceleration of the CD, as it spins...

Disk A, with a mass of 2.0 kg and a radius of 90 cm, rotates clockwise about a frictionless vertical axle at 50 rev/s. Disk B, also 2.0 kg but with a radius of 80 cm , rotates counterclockwise about that same axle, but at a greater height than disk A, at 50 rev/s. Disk B slides down the axle until it lands on top of disk A, after which they rotate together. After the collision, what is magnitude of...

The disk rotates about a fixed axis through point o with a clockwise angular velocity wo = 20 rad/s and a counterclockwise angular acceleration 0o = 4.1 rad/s2 at the instant under consideration. The value of r is 260 mm. Pin A is fixed to the disk but slides freely within the slotted member BC. Determine the velocity and acceleration of A relative to slotted member BC and the angular velocity and angular acceleration of BC. The relative velocity and...
