The figure shows a 1.50kg block at rest on a ramp of height, h. When the block is released, it reaches the bottom of the ramp and moves across a surface that is frictionless except for one section of width 10cm that has a coefficient of kinetic friction uk=0.64. Find h such that the block's speed after crossing the rough patch is 3.50m/s (Remember that the force of friction is fk=(uk)(N), where N is the normal).
