The experiment is, we put a textbook on an incline and let it go down. "find the Us"
The only force that is parallel is "Ff" , and Fg + Fn are perpendicular.
The only formula we have learned relating to this is Fsmax = Fn/Fg or Fnet = Fn - Ff - Fg like I mentioned earlier.
I gave you all I got, that's what we learned this year. I don't understand how I can solve for this Us, if just given the mass (and I can calculate the angle). I would assume, it has to do with Fg, Fn, and the angle (and of course mass)
So what I am learning is that I need to get the angle.
Like I said I watched a video earlier and he said you do Us = tan30, that seems very odd.
The formula I have familiar with is Us = F/mg but we don't have force.
Haha , yeah I know its flat in the picture, juts image it wasnt flat, I didnt want to spend too much time rotating it and stuff ( I have exams ) and, ill give it a go.
Fnet = Fn - Ff - Fg
ma = mg - μmg - mg? sorry its been 2 months since I've done forces unit, but I am assuming fg and fn...
Like I said, we have a incline plane, and we are putting a textbook ontop of it and letting it go down. We are given the mass of the textbook. We are not allowed to use kinematics or a Newton guage, so all I have is mass. I am supposed to find the Coefficient of static friction of the textbook...
See I have no calculations because I just don't understand what we are supposed to do with *JUST MASS* , I searched it up and realized a lot of people talking about angles and stuff. Can you please (not teach me) but inform me on the basics on how to use mass to find static coefficient. Here is...
Its for my final project. We are doing a sliding a textbook down an *incline plane* and we are expected to find coefficient of static friction without using Newton guage, and we are also now allowed to use kinematics. I just need some infomration on how to do this, like a formula or something in...
