Physics

The drive propeller of a ship starts from rest and acceleratesat 2.56 x 10-3 rad/s2 for 2.48 x103 s. For the next 1.47 x 103 s thepropeller rotates at a constant angular speed. Then it deceleratesat 2.80 x 10-3 rad/s2 until it slows (withoutreversing direction) to an angular speed of 2.88 rad/s. Find thetotal angular displacement of the propeller.
