well, things slow it down: 1) friction 2) the component of gravity trying to make the block slide down the plane.
Initial KE=1/2 m vi^2
work done on gravity by movement: m*g*distance/sinTheta
work done on friction: mu*mg*CosTheta*distance.
so, setting initial KE to all the others,
1/2 m vi^2= mg*distance/sinTheta+mu*mg*distance*cosTheta
solve for distance.
