Yes
You can be accelerating and traveling at a constant speed if you change directions.
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.
a car traveling the speed limit
No, speed is directionless.
The one with greater mass.
You can legally operate your vessel at greater than no-wake speed in open waters, away from defined no-wake zones, and as long as you are following the rules and regulations set forth by the local authority or waterway management. It's important to always be aware of your surroundings, other vessels, and wildlife when operating at higher speeds.
Yes
The maximum legal speed for a vessel passing under a bridge can vary depending on the location and specific regulations. In general, it is recommended to reduce speed to ensure safe passage under the bridge, typically around 5-10 knots. It is important to follow any posted regulations or guidelines for speed limits in that area.
The legal operating speed for a vessel between sunset and sunrise is typically governed by local regulations or the rules of the waterway. In general, vessels are often required to operate at a safe speed that allows them to stop or take necessary action to avoid a collision. It's important to follow the specific regulations of the area where you are operating the vessel.
No. The sonic boom will be created by any speed that is greater than the speed of sound.
Momentum is mass times velocity, if the velocity of the two are the same, the object with the greater mass will have proportionally greater momentum.
The fastest legal speed you may operate your vessel when passing within 200 feet of a dock or marina is "slow - no wake speed." This typically means operating at the slowest speed necessary to maintain steerage and headway. It is important to reduce speed to minimize the risk of causing damage or injury due to wake or other factors.
What is the maximum legal speed when the operator's view is obstructed because of people or gear on board the vessel?
If a car and a truck are traveling at the same speed, the truck would have more momentum because it has a greater mass.
the safe and legal passing of another vehicle requires that drive
50 yards or 150 feet
