The 1994 Winter Olympics included the aerials competition in skiing. In this occasion 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 men competition, the end of a typical launch ramp is directed 63degree above the horizontal. With this launch angle, a skier attains a height of 14.8 meter above the end of the ramp. Calculate what is the skier launch speed?
