How do you calculate the velocity of the boat relative to shore?

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.

How can a boat move at constant velocity if its propeller provides a steady force to it?
Terminal velocity, where the driving force = drag force from the water

Why use velocity?
If you have to fly an airplane in air with wind, or a boat in water with current, and meet a schedule, then you'll be using velocity almost before you know it, even if you don't know what to call it. And vectors too.
What is a frame of refrence?
Essentially, it's a vantage point. Mathematically speaking, a frame of reference is just a cool way of saying "this is where the observation was taken." For example, lets talk Relativity! Lets suppose a boat is passing a beech, and from the mast of the boat a sailor is dropping a coin. From the perspective of the sailor--HIS FRAME OF REFERENCE--the coin falls straight. To you, on the beech, it falls to an angle (because the boat is moving, you observe the coin falling at an angle resulting from combining the components of the velocity of the boat with the velocity of the coin as it accelerates toward the ground.) These are frames of reference.
A 4.5 kg dog stands on a 18 kg flatboat at distance 6.1 m from the shore The dog walks 2.4 m along the boat toward the shore and then stops Assuming no friction between the boat and the water find?
You can use conservation of momentum. since dP=0 than 4.5Vdog=18Vboat so Vboat=1/4Vdog because of this you know the displacement of the dog is 4x greater than the displacement of the boat. therefore Dboat=0.6m away from shore Now we must consider the momentum of the system 22.5Vsys=18Vboat+4.5Vdog (since these are Vfinals the final momentum of the dog is zero because his Vfinal is zero) so Vsys=4/5Vboat this way we know that the displacement of the system is 4/5 that of the boat so dsys=4/5(0.6)=0.48m The dog's new distance will be the original distance minus (ddog-dsys) This is 6.1-(2.4-.48)=4.18m from shore
How do calculate the velocity of the boat relative to the shore?
Add the rivers velocity to the boats velocity
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 did the Anzacs get to shore?
by boat
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
You are caught in a storm in your boat. What should you do?
Go to shore
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 long would it take to boat from Japan to Thailand?
It depends on the speed and velocity of the boat.
