Coefficient of friction between puck and ice

Click For Summary
SUMMARY

The discussion focuses on calculating the coefficient of friction between a hockey puck and ice, given a puck speed of 6.5 m/s and a distance of 7.6 m. The relevant equations include net force (fnet = ma) and frictional force (Ffr = coefficient of friction x force normal). Participants emphasize that the mass of the puck is not necessary for the calculation, as substituting known values can simplify the problem. Understanding the normal force in this context is crucial for solving the equation.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with the concepts of friction and normal force
  • Basic algebra for equation manipulation
  • Knowledge of kinematic equations
NEXT STEPS
  • Study the relationship between force, mass, and acceleration in Newton's second law
  • Learn how to calculate normal force in different scenarios
  • Explore examples of friction coefficients in sports physics
  • Practice solving problems involving kinematic equations and friction
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators teaching concepts related to motion and friction.

Homework Statement


[/B]
A hockey puck travels across the ice at 6.5m/s. the puck travels a total of 7.6m. What is the coefficient of friction between the puck and the ice.

Homework Equations


[/B]
fnet=ma
Ffr= coefficient of friction x force normal

The Attempt at a Solution


[/B]
I found my acceleration, but I feel like I cannot get the coefficient of friction without the mass. Please help.

It can be done with the 2 equations you gave. Just substitute everything you know and see if anything cancels.
 
What is the normal force equal to, in this situation?
