In the figure of this exercise a block is shown, initially located at rest at a height d = 40cm on a ramp It has horizontal zones and sloped zones. It is known that in inclined areas, the coefficient of kinetic friction between
the block and the surface is negligible; while in the horizontal zones, the coefficient of kinetic friction between the block
and the surface is µk = 0.5.

Determine where the block stops (momentarily or indefinitely). If the block stops on a surface
horizontal, determine the distance L traveled on the horizontal surface. If the block reaches the ramp,
Determine the height H (measured above the lowest horizontal surface) that the block reaches.
