Aerial skiing involves speeding down a steep ramp that curves sharply upward at the end to launch the skiers into the air. Once airborne, the skier twists and turns in complex combinations to score points in the competition. Consider an aerial launch ramp that has a final launch slope of 66.4 degrees above the horizontal. Given this angle, a skier flies to 12.4 m above the end of the ramp. From this information determine the skier's launch speed
