Homework Help Overview

The discussion revolves around representing motion using a vector diagram, specifically involving a duck paddling on a pond with given distances and angles. The problem includes drawing the vector diagram accurately and understanding the concepts of distance versus displacement.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to create a vector diagram and seeks feedback on its accuracy. Questions arise regarding the correct method for calculating total displacement using x and y components.

Discussion Status

Participants are actively providing feedback on the vector drawing methods and clarifying the distinction between distance and displacement. Some guidance has been offered regarding the proper way to draw vectors and the necessity of breaking them into components.

Contextual Notes

There is an emphasis on ensuring that vectors are drawn correctly from the tip of the previous vector, and participants are discussing the importance of understanding vector components in the context of the problem.

The question was, "In a total time of 2.0 min, a duck on a pond paddles
22 m [36deg N of E] and then paddles another 65 m [25 deg E of S]"

a) Draw a vector diagram that represents this motion. Be sure to include
a scale and compass.

I've given a new try with this diagram. Could anyone please correct it for me?
Any advice would be greatly appreciated.

Thanks for your time.

p.s / To find the Total Displacement, should I use the x & y component added together
then use the inverse tan to find the angle and direction?

check your methods for drawing vectors. After you draw the first vector you draw the second vector from the tip of previous one. If you do they way you drew the vectors check out... http://hyperphysics.phy-astr.gsu.edu/hbase/vect.html#veccon and the links within that web...that should help.

Thanks again Mindy,
I think I got it now!

What do you think?
 
also according to your drawing you have the correct distance traveled but distance and displacement are not the same thing.

Displacement is a vector so you have to break every vector into its x and y components. you can only add x components with x components and so on.

Ok ^^
Thank you very much!
