A snow$-$covered ski slope makes an angle of  slope $=38\mathrm{.}0$ degree with the horizontal. When a ski jumper plummets onto the hill, a parcel of splashed snow is thrown up to a maximum displacement of $1\mathrm{.}80$ m at snow $=18\mathrm{.}0$ degree from the vertical in the uphill direction.

 A$)$ Find the component of its maximum displacement parallel to the surface.

 B$)$ Find the component of its maximum displacement perpendicular to the surface
