Homework Help Overview

The problem involves three individuals towing a vessel and requires determining the resultant force from the forces they exert, which are represented as vectors. The context is centered around vector decomposition and the application of trigonometric functions to resolve these vectors into their components.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the method of decomposing vectors into their x and y components and the subsequent addition of these components. Questions arise regarding the specifics of the decomposition process and the application of sine and cosine functions to find the magnitudes in each direction.

Discussion Status

There is an ongoing exploration of the vector decomposition method, with participants seeking clarification on how to approach the problem. Some guidance has been offered regarding the use of trigonometric functions, but there is an emphasis on the need for participants to demonstrate their own efforts before receiving further assistance.

Contextual Notes

Participants are reminded of forum rules that require them to show their own work before receiving help. Additionally, the problem is noted as not requiring calculus, indicating it is suitable for an introductory physics context.

Homework Statement


Bjarne, Leif and Sammy are towing their vessel. The forces that they exert are directed along the tow lines, as indicated in Figure 15, which also provides the magnitudes of their forces. ( Note that in Figure 15, the force vectors are not drawn to scale.) What is the resultant force?

The Attempt at a Solution

 
Physics news on Phys.org
Decompose the vectors into their components (y and x) and add them accordingly. Do you know how to do that?
 
Could you show me the decomposition method for vectors? Adding after decomposition i should have solid idea on how to. Thank You!
 
You need to find the magnitude of the forces in the x and y direction. You do this by taking the magnitude given and using sine and cosine of the angle that they're at to find them.

We are not allowed to help you if you have done no work on the problem yourself. Those are the PF rules.
 
This is a question which does not require the use of calculus to obtain a solution. It is being moved to the Intro Physics HW forum, which is more appropriate.
 
You must show your own effort, even when you know it is wrong.
