I do not know what Mk is
Need slope of ramp and friction coefficient.
a 10kg block is allowed to slide down a ramp with Mk=0.15. what is the acceleration of the block?

By the way, the mass should not matter.
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)
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)
