9) A tug boat guides an oil tanker into port, why is it important that the tug boat make very small adjustments to direction and speed during its escort of the very massive tanker into port? 10) Sketch a graph of motion in which an object moving forwards with a positive velocity experiences a constant acceleration downwards until it reaches its starting position, at which point the acceleration suddenly becomes zero for another ten seconds. 9) A tug boat guides an oil tanker into port, why is it important that the tug boat make very small adjustments to direction and speed during its escort of the very massive tanker into port? 10) Sketch a graph of motion in which an object moving forwards with a positive velocity experiences a constant acceleration downwards until it reaches its starting position, at which point the acceleration suddenly becomes zero for another ten seconds.
