As shown in the figure below, a 2.25 kg block is released from rest on a ramp of height h. rough patch m 15.0 cm 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 coefficient of kinetic friction Mk = 0.690. Find h (in m) such that the block's speed after crossing the rough patch is 4.00 m/s. m
