A force of 160. N parallel to an inclined plane is required to move a 200. N weight up the inclined plane with a constant veloci
ty. Find the coefficient of sliding friction if the plane is inclined at 30.0 degrees.
1 answer:
- Drawing a free body diagram will help you visualize the different forces acting on an object.
- Find ∑Fy and ∑Fx and solve for unknowns; force due to kinetic friction (fk) and normal force (Fn).
- After solving for unknowns, plug values into equation for kinetic friction, fk = μk • Fn, and solve for μk
Coefficient of kinetic/sliding friction = .3464
