The 1994 Winter Olympics included the aerials competition in
skiing. In this event skiers speed down a ramp that slopes sharply
upward at the end. The sharp upward slope launches them into the
air, where they perform acrobatic maneuvers. In the women's
competition, the end of a typical launch ramp is
directed 58° above the horizontal. With this launch
angle, a skier attains a height of 13 m above the end of
the ramp. What is the skier's launch speed?
