Canít find any examples like this in my notes and my lab partner handed in theirs without even letting me see it so Iím stuck haha. Iím trying to find mu but I need Ff for that.

What you are looking for is something that is different between the
"expected" theoretical behaviour if the friction were zero and
the actual observed behaviour.

In the absence of friction; Force = Mass x Acceleration
with friction; (Force-Friction)=Mass x Acceleration.

Be a little bit careful just following the above word for word,
I have just sketched out the idea,
you will have to fit it to your experiment.
