Homework Help Overview

The problem involves an electron shot at a specific speed and angle through a uniform electric field, with the goal of determining the y component of its velocity upon hitting a detection screen positioned at a certain distance. The subject area includes kinematics and electric forces.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss breaking down the initial velocity into x and y components and question how to incorporate the electric field into their calculations. There is confusion about the relationship between acceleration and the y component of velocity, as well as how to apply the equations of motion.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem and attempting various calculations. Some guidance has been provided regarding the relationship between force, acceleration, and velocity, but no consensus has been reached on the final approach to the solution.

Contextual Notes

Participants are working under the constraints of a homework assignment, which may limit the information they can use or the methods they can apply. There is also a focus on ensuring the correct interpretation of the question regarding the y component of velocity.

You're now answering a question regarding velocity, not position so it has different units than the last time you asked about units.

* face palm * I need to stop doing homework so late, I got it now. Thank you soooo much for your help and time. I really appreciate it! This will certainly be a question I'll review for an upcoming exam :smile:

You're welcome.

Time for me to get some sleep too.
