a 10kg block is allowed to slide down a ramp with Mk=0.15. what is the acceleration of the block?

slope of ramp? 
Damon,
I do not know what Mk is
Need slope of ramp and friction coefficient. 
physics 
Damon,
By the way, the mass should not matter.

physics 
drwls,
The numerical value of acceleration, a, will depend upon the angle of the block. Call that angle "A".
Acclerating force = M g sin A
Friction force = M g cos * Mk
Mg(sin A  Mk cos A) = M a
a = g(sinA  Mk*cosA)
