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

Frictional Force 2: Find Coefficient of Kinetic Friction on Ice

Click For Summary
The discussion revolves around calculating the coefficient of kinetic friction for a hockey puck sliding on ice. The problem involves determining the puck's initial velocity and acceleration using kinematic equations, given its displacement and time until it comes to rest. Participants emphasize the importance of setting up a system of equations to solve for the unknowns, specifically using the equations of motion. After deriving the acceleration, they apply Newton's second law to relate the forces acting on the puck to find the coefficient of friction. The final calculated value for the coefficient of kinetic friction is approximately 0.0637, which is dimensionless.

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?
