Homework Help: physics

Posted by Marco on Thursday, November 10, 2011 at 2:22am.

The drive propeller of a ship starts from rest and accelerates at 3.00 10-3 rad/s2 for 2.05 103 s. For the next 1.75 103 s the propeller rotates at a constant angular speed. Then it decelerates at 2.30 10-3 rad/s2 until it slows (without reversing direction) to an angular speed of 4.00 rad/s. Find the total angular displacement of the propeller.
