A computer hard disk starts from rest, then speeds up with an angular acceleration of 200.0 rad/s2 until it reaches a final angular speed of 7300.0 rpm.

(a) What is the final angular speed in units of rad/s?

rad/s.

(b) How long does it take for the disk to reach this angular speed?

rev

(d) Once the disk reaches its final angular speed, it continues rotating at this same speed. How many revolutions has the disk made 10.0 s after it started up from rest? NOTE: The 10.0 s includes the time to take the disk to get up to full speed, and any additional time to get to 10.0 total seconds.
