If a river current is 8.0 meters per second and a boat is traveling 10.0 meters per second upstream what is the boat's speed relative to the riverbank?
ans is = 10 - 8 = 2 m/s (upstream)
What else can I help you with?
What is the greatest velocity that a boat on a river can attain if the boat's motor moves at 10 km per hr and the river's current is 8 km per hr?
Boat WRT land, downstream 10 + 8 = 18 KMH Boat WRT land, upstream 10 - 8 = 2 KMH Boat WRT water 10 KMH
A motorboat takes 5 hours to travel 300 km going upstream The return trip takes 2 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Velocity = Distance ÷ Time.The speed upstream = 300 ÷ 5 = 60kph.The speed downstream = 300 ÷ 2 = 150 kph.The speed upstream equals boat velocity(Vb) minus current velocity(Vc).The speed downstream equals boat velocity (Vb) pluscurrent velocity (Vc).Vb - Vc = 60Vb + Vc = 150 : Adding the two equations together gives :-2Vb = 210 : Vb = 105, therefore Vc = 45The rate of the boat in still water is 105 kph. The rate of the current is 45 kph.
A motor boat can go 2 miles downstream on a river in 3 minutes it takes 15 minutes for the boat to go upstream the same 2 miles find the speed of the current?
Let boat speed = X and current speed = Y Downstream speed = boat speed plus current speed = X + Y Upstream speed = boat speed minus current speed = X -Y Downstream speed = 2 miles divided by 3 minutes = 2/3 miles per minute Upstream speed = 2 miles divided by 15 minutes = 2/15 miles per minute X + Y = 2/3 X - Y = 2/15 add equations 2X = 2/3 + 2/15 = 10/15 + 2/15 = 12/15 = 4/5 divide by 2 X = 4/10 = 2/5 use second equation and find Y as X -Y = 2/15 2/5 - Y = 2/15 6/15 - Y = 2/15 Y = 4/15 = current speed = 0.266 miles per minute
How old would you be if you were born in 1995 and its 2013?
Oh, dude, if you were born in 1995 and it's 2013, you would be like 18 years old. I mean, it's not rocket science, right? Just subtract the birth year from the current year and bam, you got your answer. Math, man, it's wild.
An example of liquidity ratio is the?
current ratio and acid test ratio are examples of liquidity ratios'. current ratio is current asset's/ current liabilities. acid test ratio is current assets- stock / current liabilities.
8.0 m per s and a boat is traveling 10.0 m per s upstream what is the boats speed relative to the riverbank?
f a river current is 8.0 m/s, and a boat is traveling 10.0 m/s upstream, what is the boat's speed relative to the riverbank?
If a river current is 8.0 miles per second and a boat is traveling 10.0 miles per second upstream what is the boat's speed relative to the riverbank?
2 miles per second upstream relative to the river bank.Note: This is quite a scenario, even for experienced rapids-shooters.That river is flowing at 28,800 miles per hour, and the guy is paddlinghis kayak through the water at 36,000 miles per hour. The whole sceneis definitely poised to launch itself into solar orbit.
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.
How do you ferry a current?
In order to ferry a current you need to point your boat an an angle across the river and pointing upstream. The stronger the current the more you will have to point upstream. You simply paddle at this angle until you reach the other side. It also can help if you lift your upstream knee slightly so that the water doesn't catch your upstream edge.
A motorboat maintained a constant speed of 24 miles per hour relative to the water going 35 miles upstream and then returning the total time for the trip was 3.0 hours What is the speed of current?
The current speed is about 4 miles per hour.
How do you set up the equation to find current of a river?
To set up the equation for finding the current of a river, you typically consider the speed of a boat relative to the water and the speed of the boat relative to the ground. Let ( v_b ) be the speed of the boat in still water, ( v_r ) be the speed of the river current, and ( v_g ) be the speed of the boat relative to the ground. The equation can be expressed as ( v_g = v_b + v_r ) when the boat is moving downstream and ( v_g = v_b - v_r ) when moving upstream. By measuring the ground speed in both directions, you can solve for ( v_r ).
What does it mean swimming up stream?
Swimming upstream is to do something the hard way. It is more difficult to swim against the current. Salmon swim upstream in order to spawn.
Why did the ferry boat have to go upstream before crossing the river?
if the boat turns toward the dock without going upstream, it will miss it's mark because the current is pushing the boat downstream.
If a fishing boat travels 15mph in still waters how long will it take it to travel 30 miles upstream with a current of 3?
The boat travels past the water around it at 15 mph.If the water is moving past the riverbank at 3 mph, then the boat is moving past the riverbankat (15 - 3) = 12 mph.At 12 mph, it takes (30/12) = 2-1/2 hours (2hr 30min) to travel 30 miles up the riverbank.Coming back, the boat's speed past the riverbank will be (15+3) = 18 mph.It will take (30/18) = 1-2/3 hours (1hr 40min) to travel 30 miles down the riverbank.
Is a floating leaf said to be in motion with respect to a stream?
No. Assuming there are no eddies or crosscurrents, and it is not blown in a different direction by the wind, a leaf in a stream is being moved by the water, and would display little motion with respect to the water, as compared to its motion with respect to things not in the flowing stream.
Can earth fault current go up passing through the downstream panel and directly cause a trip at the upstream panel which have higher set point of earth fault protection?
If the fault is a direct short to ground, the fault current can be high enough to trip the upstream protection.
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.
