Homework Help Overview

The discussion revolves around calculating the speed of a fishing boat in a river with a current. The problem involves understanding the relationship between the boat's velocity and the river's flow, specifically addressing maximum and minimum speeds.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants explore the maximum velocity of the boat in relation to the river's current, questioning whether it can reach 4m/s. There is also a focus on determining the minimum speed of the boat with respect to the riverbank, with some participants suggesting it could be 0 m/s.

Discussion Status

The discussion includes various interpretations of the boat's speed relative to the riverbank. Some participants have provided guidance on how to approach the problem, particularly regarding the effects of the river's current on the boat's movement.

Contextual Notes

There is an ongoing exploration of the definitions of speed and velocity, as well as the implications of the river's flow direction on the boat's movement. Participants are considering the setup of the problem and the assumptions involved in calculating the speeds.

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?
is it 4m/s?"

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?
 
Yep!
 
thanks ;]
 
You're welcome.
