Question

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 directed66°above the horizontal. With this launch angle, a skier attains aheight of 12 m above the end of theramp. What is the skier's launch speed? Iv gotten 18.7m/s, and 18.8m/s two different ways and it isnot the correct answer. help?? The 1994 Winter Olympics included the aerials competition inskiing.

u*u sin266/19.6=12
so launch speed=u=16.788m/sec
