That should be right. Is there a way you can check it?

Homework Help Overview
This discussion revolves around a physics problem concerning the coefficient of kinetic friction between a hockey puck and ice. The scenario involves a puck sliding a distance of 20.0 meters across a frozen pond in 8.0 seconds before coming to a stop.
Discussion Character
- Exploratory, Conceptual clarification, Mathematical reasoning, Problem interpretation
Approaches and Questions Raised
- Participants discuss using kinematic equations to determine the puck's initial velocity and acceleration. There are questions about the appropriateness of specific equations and how to rearrange them to isolate variables. Some participants express confusion about the relationship between acceleration and initial velocity.
Discussion Status
The conversation has progressed through various attempts to apply kinematic equations, with participants sharing insights and corrections. There is an ongoing exploration of the relationships between the variables involved, and some participants are beginning to derive values for acceleration and initial velocity. However, there is no explicit consensus on the final approach or solution.
Contextual Notes
Participants are navigating the constraints of the problem, including the need to derive initial conditions and the effects of friction without complete information about forces acting on the puck. The discussion reflects the challenges of working through physics problems in a collaborative setting.

I trust the work is accurate. Thank you for staying up with me until 5AM for some homework that you could have probably done in 20 minutes.
If you have the time, could you check my reasoning on this problem as well?
