Blocks speed after crossing the rough patch

Reference no: EM13651036

A 1.75 kg block at rest on a ramp of height h. When the block isreleased, it slides without friction to the bottom of the ramp, andthen continues across a surface that is frictionless except for arough patch of width 10.0 cm that has a coefficient of kineticfriction μk=0.640. Find h such that the block's speed after crossing the rough patch is 3.50 m/s.
