The velocity of a boat relative to the shore is also known as 'Speed over ground' can be established by two main methods.
1. Speed over ground can be established as average speed over ground, by making two position fixes in the chart, using the compass bearings towards at least two shore objects in each of the fixes and writing down the time. The average speed
AvSpeed = Distance covered (measured in the chart) / Time elapsed between the two fixes.
A fix is a determination of the boat position using landmarks shown in the chart.
2. Using a GPS (Global Positioning System). A modern GPS gives you the instant speed over the ground. Using the distance travelled (registered by the GPS) and the elapsed time (also recorded by the GPS) you can calculate the average speed over ground (average velocity relative to shore). Some GPS units can calculate this average speed, if you reset the distance travelled and time elapsed data on the GPS when you start your navigation.
What else can I help you with?
A river current has a velocity of 5 kmh relative to the shore. A boat moves in the same direction as the current at 4 kmh relative to the river. How do you calculate the velocity of the boat relative?
The velocity of the boat relative to the shore is the vector sum of its velocity relative to the river and the velocity of the river current. In this case, it would be 4 km/h (boat's speed) + 5 km/h (current's speed), which equals 9 km/h.
What would happen to a boat that was moving upstream at the same speed as the current moving downstream?
If the boat is moving upstream at the same speed as the current moving downstream, the boat will appear to be stationary relative to an observer on the shore. This is because the boat's upstream motion is being cancelled out by the downstream motion of the current.
What are some relative velocity practice problems that can help me improve my understanding of the concept?
One example of a relative velocity practice problem is: Two cars are traveling in the same direction on a highway. Car A is moving at 60 mph and car B is moving at 70 mph. If car A is 100 meters behind car B, how long will it take for car A to catch up to car B? Another example is: A boat is moving downstream in a river at a speed of 5 m/s. If the river is flowing at a speed of 2 m/s, what is the boat's speed relative to the riverbank? Solving these types of problems can help improve your understanding of relative velocity concepts.
How can a boat move at constant velocity if its propeller provides a steady force to it?
A boat moves at a constant velocity if the force provided by the propeller exactly balances the resistive forces such as drag and friction acting on the boat. Once the forces are balanced, the boat will continue moving at a constant velocity as long as the propeller keeps applying the same force.
A boat moves at a speed of 15 kmh in still water. The river it is traveling in flows at a rate of 3 kmh downstream. What is the velocity of the boat if it travels downstream What is the velocity of th?
If the boat is moving downstream, you add the speed of the boat with the speed of the river flow. Therefore, the velocity of the boat downstream is 18 km/h. If the boat is moving upstream, you subtract the river flow speed from the boat's speed, so in this case, it would be 12 km/h.
How do calculate the velocity of the boat relative to the shore?
Add the rivers velocity to the boats velocity
A river current has a velocity of 5 kmh relative to the shore. A boat moves in the same direction as the current at 4 kmh relative to the river. How do you calculate the velocity of the boat relative?
The velocity of the boat relative to the shore is the vector sum of its velocity relative to the river and the velocity of the river current. In this case, it would be 4 km/h (boat's speed) + 5 km/h (current's speed), which equals 9 km/h.
A boat whose velocity through the water is 14 kmh is moving in a river whose current is 6 kmin relative to the riverbed The velocity of the boat relative to the riverbed must be between?
13.9 km hr
A boat heading north crosses a wide river with a speed of 10kmhr relative to water the river has a speed of 5kmhr due east what is the velocity of the boat w respect to a stationary ground observer?
Use Pythagoras' theorem to calculate the magnitude of the velocity (the speed): Sqrt(10^2 + 5^2) = sqrt(125) = 11.2 km/h
How do you make this sentence into an alliteration marching down to their boat on the shore?
stomping down to their boats on the sad shore
How did the Anzacs get to shore?
by boat
What would happen to a boat that was moving upstream at the same speed as the current moving downstream?
If the boat is moving upstream at the same speed as the current moving downstream, the boat will appear to be stationary relative to an observer on the shore. This is because the boat's upstream motion is being cancelled out by the downstream motion of the current.
Did the German U boat attack on the Jersey Shore?
No, but the German me boat did.
What is the boat used for passenger from ship to shore?
a boat used to transport passengers between a cruise ship and shore in shallow waters
Where does pushing the boat out come from?
Launching from shore.
When you step shore from a rowing boat it tends to leave the shore?
This is an example of 'action' and 'reaction'. Every 'action', like stepping out of the boat on to the shore causes an equal and opposite 'reaction', as the boat moves in the opposite direction. This is also how rockets move in the vacuum of space.
How this situation explain newton's third law when throwing a package onto shore from a boat that was previously at rest causes the boat to move outward from shore?
when boat is at rest gravity is pulling mass inside a boat down ward as a reaction strength of boat keep the object in the boat when we ttrow a package on to a shore the mass of boat decrease and G also decrease and reaction force which is upward cause the boat to go up
