The 1994 Winter Olympics included the aerials competition inskiing. In this event skiers speed down a ramp that slopes sharplyupward at the end. The sharp upward slope launches them into theair, where they perform acrobatic maneuvers. In the women'scompetition, the end of a typical launch ramp is directed63° above the horizontal. With this launch angle, a skier attains a height of13 m above the end of the ramp. What isthe skier's launch speed?
