The figure shows a 1.75-{\rm kg} block at rest on a ramp of heighth. When the block is released, it slides without friction to thebottom of the ramp, and then continues across a surface that isfrictionless except for a rough patch of width 10.0 {\rm cm} thathas a coefficient of kinetic friction 0.650.
Find h such that the block's speed after crossing the rough patchis 3.60 {\rm m/s}.
