The drive propeller of a ship starts from rest and accelerates at 2.99 x 103 rad/s² for 2.05 x 10³ s. For the next 1.20 x 10³s the propeller rotates at a constant angular speed. Then it decelerates at 2.45 x 10-3 rad/s² until it slows (without reversing direction) to an angular speed of 2.11 rad/s. Find the total angular displacement of the propeller. Number Units
