As shown in the gure below, a 2.25 kg block is released from rest on a ramp of height h. _. 1 4" mugh patch 15.0 cm (D When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefcient of kinetic friction \"k = 0.630. Find h (in m) such that the block's speed alter crossing the rough patch is 3.20 m/s. (Enter a number.) m
