A compact disc rotates from rest up to an angular speed of 34.3 rad/s in a time of 0.867 s.

(a) What is the angular acceleration of the disc, assuming the angular acceleration is uniform?
rad/s²

(b) Through what angle does the disc turn while coming up to speed?
rad

(c) If the radius of the disc is 4.45 cm, find the tangential speed of a microbe riding on the rim of the disc.
m/s

(d) What is the magnitude of the tangential acceleration of the microbe at the given time?
m/s²

Use the values from above to help you work this exercise.
(a) What are the angular speed and angular displacement of the disc 0.340 s after it begins to rotate?
