1. I need to set up a lab. The goal is to find the force of friction between a track and a ball. The track is flexible and tilted so that it slopes down. Looking at it from the side, the track looks like half of a U. The ball is released from the top of the track and somehow I have to figure out the friction.(adsbygoogle = window.adsbygoogle || []).push({});

2. Force of friction=u* normal force

Fnet=ma

delta y =Voy*t+1/2at^2

]3. If I just found the mass of ball, roll it down the track and time it, then plug into the distance equation to solve for acceleration, then take that into the f=ma equation, would that give me the answer? I am not sure how the force of friction is related to the net force, or how to find this without knowing the coefficient of friction.
