im doing a Force and acceleration lab. I need to collect data for force friction. If I already have mass, distance, time, final velocity, acceleration, force(f=ma), (Fg=mg).
How do I solve for Force friction? What do i need in that list.
Question 2 (if possible)
How do you get Force myu (u) if I have mass, Fg, Ff(kinetic), and F.
How do you get Force myu in this case?
Thanks for your help

the best way to anwer this is to just look at the siatio you are experimenting with and to make a free body diagram. (in physics a free body diagram is always the first step)
you know the total force is equal to ma (note this sit eh summation of forces applied). I am not sure of the setup you have for the experiment. So I will make one up.
Say you calculate that to drag a block such that it's velocity was constant. then you would know that a is 0, so the summation of forces would be zero. you would have f=ma=0=force of tension-force of friction. the force of friction opposes the tension because they are in different directions, however because the velocity is zero we know tha the magnitude of the two must be equal. So if yo did this expriment with a force meter attached to tyour spring, whatever force it read would be the force of friction. Mu would just be this force divded by mg which would be the normal force.

F = ma, 1200 x 1.5/0.75 = 2400N. 0.020 N is a tiny force which would not move the car. 1.5/0/75 is the accel (vel / time)
