(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A hockey puck leaves a player's stick with a speed of 8.30m/s and slides 25.0m before coming to rest.

Find the coefficient of friction between the puck and the ice.

2. Relevant equations

f=μn

F=ma

v^2=v_0^2+2a(x-x_0)

3. The attempt at a solution

So I've already figured out the acceleration of the puck using the third equation I listed, which came out to be 12.5m/s. Problem is, I can't figure out how to find the mass of the puck. Which I need to know in order to calculate the normal force. Even then, I would still have two variables since I don't know (f) or (μ) where I'm trying to find (μ).

Help please? :)
