The drive propeller of a ship starts from rest and accelerates at 2.23×10−3 rad/s2 for 2.81 x 103 s. For the next 1.35×103 s the propeller rotates at a constant angular speed. Then it decelerates at 2.28×10−3 rad/s2 until it slows (without reversing direction) to an angular speed of 2.55 rad/s. Find the total angular displacement of the propeller. Number Units

The drive propeller of a ship starts from rest and accelerates at

2.23 \times 10^{- 3} r a d / s^{2}

for

2.81 x

10^{3} s

. For the next

1.35 \times 10^{3} s

the propeller rotates at a constant angular speed. Then it decelerates at

2.28 \times 10^{- 3} r a d / s^{2}

untilit slows (without reversing direction) to an angular speed of

2.55 r a d / s

. Find the total angular displacement of the propeller.
