The 1994 Winter Olympics included the aerials in skiing. In this event skiers speed down a ramp that sloped sharply at the end. The sharp upward slope launches then into the air, where they perform acrobatic maneuvers. In the women's competition, the end of a typical ramp is directed 63o above the horizontal. With this angle, a skier attains a height of 13 meter above the end of the ramp. Evaluate what is the skier launch speed?
