Calculating Speed of a Fishing Boat in a River

In summary, the maximum velocity a fishing boat can obtain in a river with a flow of 2m/s west is 4m/s west. The minimum speed is 0m/s, as the boat would appear to be stationary to someone standing on the riverbank.

A fishing boat with a max. velocity of 2m/s is in a river that is flowing at 2m/s west.

a. what is the maximum velocity the boat can obtain?
is it 4m/s?


b. what is the minimum speed?
this question i need help answering...

"a. what is the maximum velocity the boat can obtain?

The max speed is 4m/s; the max velocity is 4m/s west (magnitude and direction).

For part b, if you boat goes 2m/s east with respect to the water, and the water goes 2m/s west with repect to the river bank, what is the boat's speed with respect to the river bank? How would the boat appear to be moving to someone standing on the riverbank?

so it should be 0 m/s?
 
  • #4
Yep!

Related to Calculating Speed of a Fishing Boat in a River

1. How do you calculate the speed of a fishing boat in a river?

To calculate the speed of a fishing boat in a river, you will need to measure the distance traveled and the time it took to travel that distance. Then, you can divide the distance by the time to get the average speed.

2. What is the formula for calculating speed?

The formula for calculating speed is speed = distance / time. This means that the speed is equal to the distance traveled divided by the time it took to travel that distance.

3. What units are used for measuring speed?

The most commonly used units for measuring speed are meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph). However, other units such as feet per second (ft/s) and knots (nautical miles per hour) are also used in specific contexts.

4. How does the direction of the river affect the speed of the fishing boat?

The direction of the river can affect the speed of the fishing boat. If the boat is traveling downstream with the current, it will have a higher speed compared to traveling upstream against the current. The current can also cause the boat to drift, which can affect the overall speed.

5. Can the speed of a fishing boat in a river be affected by other factors?

Yes, the speed of a fishing boat in a river can be affected by other factors such as wind, waves, and the weight of the boat and its contents. These factors can either increase or decrease the speed of the boat and should be taken into consideration when calculating the speed.
