Homework Help: Acceleration given kinetic friction

  1. Oct 1, 2009 #1
    1. A crate is sliding down a ramp that is inclined at an angle of 51.1° above the horizontal. The coefficient of kinetic friction between the crate and the ramp surface is 1.171. Find the acceleration of the moving crate.

    2. Fnet = mass of object x acceleration

    3. Sine I don't have the mass, I'm not sure what to plug into the equation. Can someone walk me through how to solve it?
