Im designing a lab, in which i need to find the kinetic μ for a specific surface by sliding 6 different masses from the top, and taking the time it takes to reach the bottom. This surface is 30 degrees from the floor, making it a ramp. I will know the distance the masses cover.(adsbygoogle = window.adsbygoogle || []).push({});

Some relevant equations are -

F=ma

Ff=Nμ

Fr=F-Ff

d=vi(t)+(at^2)/2

v=d/t

What i did was to, drop the 6 masses from the top and take the time it takes to get to the bottom. From there u can find the v and acceleration. According to me, with acceleration you can find the Force of friction since you know the normal....I'm not sure if this is correct. If wrong, what do i need to find the μ of a surface in an experiment.

Thanks
