Bird's total displacement in polar notation

Click For Summary

Homework Help Overview

The problem involves calculating the total displacement of a bird that flies in two segments, with specified distances and angles. The subject area pertains to vector addition and displacement in a two-dimensional plane.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss finding the components of each vector and how to add or subtract them appropriately. There are questions about the degree measurement and the accuracy of their calculations.

Discussion Status

Some participants have shared their attempts at calculating the components of the vectors, while others express confusion over the addition of these components and the resulting angle. There is an ongoing exploration of how to correctly visualize and compute the total displacement.

Contextual Notes

Participants are working under the constraints of homework rules, which may limit the type of guidance that can be provided. There is also mention of difficulties in achieving the correct answer despite attempts to follow the vector addition process.

1. A bird flies 5.00 m at 50.0° and then 3.00 m at −30.0°. What is the bird's total displacement in polar notation

Show your attempt.
 


well i know to find the totals displacement you need to find the components of each vector so they were 3.83 and 3.21 for the first part and 2.6 and 1.5 for the second part
 


If you draw the vectors, you can see that which components should be added and which components should be subtracted.
 


even when i do that i continue to get the wrong answer and I do not know how to figure out the degree measurement
 


Please show your calculations.
