At the start of a CD it is spinning at a rate of 533 rpm (revolutions per minute). Just as the CD finishes playing it is spinning at a rate of 241 rpm. While playing, the CD undergoes a constant angular acceleration of -7.65·10-3 rad/s2.
Find the angle through which the CD has rotated during its playing time.
(in rad)

B)Find the playing time.

    QUESTION: An electric motor is required to complete exactly 10000 revolutions from the start of its motion to the end of its motion. Starting from rest the motor undergoes a constant angular acceleration of 120 rad s-2 for 6.00 s to reach its top angular velocity. It then remains at this top angular velocity for exactly 1 minute and is then brought to rest (constant angular retardation). Use an angular velocity-time diagram to help calculate the following: 1)Calculate the top...

    Constants Part A A high-speed flywheel in a motor is spinning at 500 rpm (revolutions per minute) when a power failure suddenly occurs. The flywheel has mass 39.0 kg and diameter 79.0 cm. The power is off for 25.0 s and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 150 complete revolutions. At what rate is the flywheel spinning when the power comes back on?...

    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...
