Homework Help: Physics (Mechanics)

Posted by Anonymous on Sunday, September 30, 2012 at 5:36pm.

A 10-kg crate on a ramp is inclined at 30 degrees from the horizontal and released. The coefficients of friction between them are .48 (coefficient of static friction) and .28 (coefficient of kinetic friction).

a) Does the block slide?
b) What then is the actual friction force?

I'm a little confused on this so any help would be greatly appreciated.
