A 1.75 kg blcok is at rest on a ramp of height h. Whentheblock is released, it slides without friction to the bottom oftheramp, and then continues across a surface that isfrictionlessexcept for a rough patch of width 10.0 cm that has acoefficient ofkinetic friction μk = 0.640. Find h suchthat theblock's speed after crossing the rough patch is 3.50 m/s.
