Hi all, me with a few physics problems.

Click For Summary

Homework Help Overview

The discussion involves multiple physics problems related to kinematics, forces, and tension. Participants are attempting to understand how to approach these problems without seeking direct answers, focusing instead on the reasoning and equations involved.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need for kinematic equations and how to apply them to the problems presented. There is an exploration of breaking down velocities into components and the implications of vertical and horizontal motion.

Discussion Status

Some participants are actively engaging with the problems, asking clarifying questions about the equations and concepts. There is a recognition of the need to understand the relationships between different variables, although no consensus or resolution has been reached.

Contextual Notes

Participants express uncertainty about the equations and their applications, indicating a lack of familiarity with the subject matter. There are mentions of specific values and conditions that are not fully defined, contributing to the complexity of the discussion.

Correct, so using vf = vi+at we can write;

v -gt = 0 \Rightarrow t = -\frac{v}{g}

Do you follow?


okay yea, I follow.

I'm sorry, I don't know. It seems like we're going in circles. I'm looking at this stuff and d is the only number I have. Everything else is equal to other thigns I don't know. Like T, I understand that t = -v/g, but how do I get v? is g just 9.8?
