Relative Motion Homework: Snow Falling Angle at 6.9 m/s, 79 km/h

Click For Summary

Homework Help Overview

The problem involves analyzing the relative motion of snowflakes falling vertically while a car is moving horizontally. The snow falls at a speed of 6.9 m/s, and the car's speed is given as 79 km/h, which participants convert to meters per second for analysis.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the conversion of the car's speed from km/h to m/s and express uncertainty about how to proceed with the information. There is a suggestion to consider the relationship between vertical and horizontal motion to find an angle.

Discussion Status

The discussion is ongoing, with participants attempting to clarify the problem setup and explore the relationship between the vertical and horizontal components of motion. Some guidance is offered regarding the conversion of units and the potential for finding an angle, but no consensus or resolution has been reached.

Contextual Notes

Participants express confusion about how to utilize the given speeds and are seeking direction on how to approach the problem. There is an emphasis on understanding the relationship between the two motions involved.

Ok so that is 21.94 m/s right? I don't know what to do with this info! I am so lost!

The snow is falling vertically at 6.9m/s.

As you look out the window it is also moving horizontally at 21.94m/s

Let's see. Vertically ... horizontally ... hmmm. Think there might be an angle in there somewhere?
