Homework Help Overview

The problem involves a ship's movement described by a series of directional distances: 50 km east, 40 km north, and 20 km west, over a time period of 6 hours. The task is to calculate distance travelled, displacement, average speed, and average velocity.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants express uncertainty about how to approach the problem. Some suggest drawing vectors to visualize the movement and adding magnitudes to determine total distance. Others mention the need to calculate average speed and average velocity based on the total distance and displacement.

Discussion Status

The discussion is ongoing, with participants providing hints and suggestions for visualizing the problem through vector diagrams. There is a recognition of the need to calculate various quantities, but no consensus has been reached on a specific method or solution.

Contextual Notes

Some participants note the importance of showing work and following homework guidelines, indicating that there may be expectations for the level of detail in responses.

ship is moving;
draw the four geographical directions and draw the movement vectors with arrow and then add the magnitude to get total distance ...etc.

The question asks for several answers. I'm sure you can work out the first (distance traveled).

Hints:
1. Ship is moving and taking turns- hope you have drawn the vectors - so you know by adding magnitudes the total distance covered.. sayD
2. so now you can calculate average speed you have time spent in covering that total distance D.
3. the total displacement will be vector sum of the displacement- you know how to add vectors -the average velocity which is a vector can be calculated using total displacement and time taken as rate of change of displacement.
