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

SUMMARY
The discussion focuses on calculating the coefficient of kinetic friction between a hockey puck and ice after it slides 20.0 meters in 8.0 seconds. Participants utilize kinematic equations, specifically x = x0 + v0t + (1/2)at^2 and v = v0 + at, to derive the initial velocity and acceleration of the puck. The final coefficient of kinetic friction is calculated to be μ = 0.0637, demonstrating the application of Newton's second law and frictional force concepts.
PREREQUISITES- Understanding of kinematic equations, specifically x = x0 + v0t + (1/2)at^2 and v = v0 + at

- Familiarity with the concept of friction and the formula for frictional force, F_friction = μFn
- Basic algebra skills for solving equations with multiple variables
- Study the derivation and application of kinematic equations in various physics problems
- Explore the relationship between frictional force and acceleration in different materials
- Learn about the factors affecting the coefficient of kinetic friction in real-world scenarios
- Investigate the implications of Newton's laws in dynamic systems involving friction
Students in physics courses, educators teaching physical science, and anyone interested in understanding the principles of motion and friction in real-world applications.

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?
