Question

The drive propeller of a ship starts from rest and accelerates at 2.8 x 10-3 rad/s2 for 2.1 x 103 s. For the next 5 x 103 s the propeller rotates at a constant angular speed. Then it decelerates at 5 x 10-3 rad/s2 until it slows (without reversing direction) to an angular speed of 8 rad/s. Find the total angular displacement of the propeller. Do not put units in answer. Do not put answer in scientific notation
