Usually unders 55 or 60 mph and varied speeds. The speed of running in a new engine is really not important. The important thing is, never over rev the engine and never let the engine labour. If you avoid both of these then the engine should stay sound for many miles. modern cars don't need an elaberate break in period. Just don't be stupid and burn out alot or redline every time you shift. Drive like a sensible person for the first 15,000 miles or so. -if its diesel then run it hard. it makes the engine last longer BUT only on diesels, if its gas then take it easy but not granny style
This depends on your speed and may depend on what country you live in. Where I live you should travel at a distance suitable for the speed you are traveling.
cruising speed
You can be accelerating and traveling at a constant speed if you change directions.
RPM varies with what gear you are in and what speed you are traveling at.
AN airplane traveling @ a constant speed. It's air friction is balanced by the applied force of it's engine.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
The engine will stop, but the PWC will continue forward and you will have no control over the speed or direction in which you are traveling... not a good thing to do in busy areas.

When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
True
No wake speed varies from state to state. In Arizona, the term used is wakeless speed. It is defined as "a speed that does not cause the watercraft to create a wake, but in no case in excess of five miles per hour." The general interpretation is that if your watercraft creates such a wake that it breaks, or otherwise generates what is called "white water", or water that has been disturbed enough that it creates bubbles or visible waves of any size, you are traveling above no wake speed. If you place your watercraft engine in gear, and add no additional engine speed once the propeller engages, you should be traveling at an adequate speed to not generate a wake; idle speed. I would say this could be from 600-800 engine RPM's. Check your specific state's boating laws, however, to find the correct interpretation of no wake or wakeless speed in your state.
