Force of Friction

  • #1

Homework Statement


Mass: .034kg
Acceleration: -.3644
Time:2.744sec
Inital Velocity: 1m/s
The path is on a flat surface

Homework Equations


Ff=mu(Fn)
F=m*a

The Attempt at a Solution


I need help find the coefficient of friction. I'm trying to find the difference of mu between oil, water, and a dry surface, and I lack Ff, or I do not know how to find it without mu. Is there anyway to find the solution. Thank you

Unless you were given varying information for each case, you'd need to look those μ values up in a table

You know the mass and the acceleration.
What/who's law relates Force, mass and acceleration?
