The drive propeller of a ship starts from rest and accelerates at 2.1 x 10-3 rad/s2 for 2.1 x 103 s. For the next 2 x 103 s the propeller rotates at a constant angular speed. Then it decelerates at 2 x 10-3 rad/s2 until it slows (without reversing direction) to an angular speed of 7 rad/s. Find the total angular displacement of the propeller.

A Train on a straight railway track starts from rest and accelerates at 2.0 m/s2 in 10sec. Then the train covers a distance of 300 m at constant speed for 20 sec until the brakes are applied, stopping the train in a uniform manner in an additional 5.0 s. (a) How far is the train in first 30sec? (b) What is the average velocity of the train for the complete journey?
