Friction on an inclined plane

[athanasia]

I need help with a problem. In the book, the mass, the elevation of the inclined plane, and the acceleration are given. I am told to find the kinetic Friction coefficient. What equation(s) would I use to solve this problem?

You have to read more of the book than just the problems!

You'll need to understand F_net = ma; you'll need to identify the forces acting on the mass; you'll need to find the components of those forces parallel and perpendicular to the surface of the plane; you'll need to understand that F_friction = μN, where N is the normal force.

Have fun!
