A skateboarder shoots off a ramp with a velocity of 6.9 m/s, directed at an angle of 54° above the horizontal. The end of the ramp is 1.1 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp.
