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

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.
