1. A rotating machine starts at 1.7 revolution and an initial angular speed of 4.5 revolutions per second and accelerates at 2.53 revolutions/s2 for 0.5 seconds. What is the ending angle in revolutions at the end of this time? 2. A DJ speeds up a turntable uniformly from 13.0 rpm to 93.1 rpm. In doing so, the turntable goes through 34.1 revolutions. What is the angular acceleration of the table in revolutions per minute per minute (rpm2)?

3. A washing machine spin-dries clothes. It starts spinning at 932 deg/s and slows down to 221 deg/s while turning through 908.7 degrees. How long does this take in seconds?

4. A CD player spins at 296 rps --. If it starts from rest and has an acceleration of 3.97 rad/s^2, how long does it take to reach full speed, answer in seconds?

5. A rotating machine has an initial angular speed of 18.3 rad/s decelerates (negative folks) uniformly at a rate of -9.2 rad/s2 for 5.0 seconds. How fast is the object rotating in rad/sec after 5.1 seconds?
