The drive propeller of a ship starts from rest and accelerates at 2.90 × 10-3 rad/s2 for 2.10 × 103 s. For the next 1.40 × 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.
