Please Help...
Can Someone please help me with these 2 physics question..i don't know waht equation to use ...can someone please tell me what equation to use..thanks alot..appreciate it.
1.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 63 degrees above the horizontal. With this launch angle, a skier attains a height of 12.0 m above the end of the ramp. What is the skier's launch speed?
2. Suppose the water at the top of Niagara Falls has a horizontal speed of 4.88 m/s just before it cascades over the edge of the falls. At what vertical distance below the edge does the velocity vector of the water point downward at a 52.3 degrees angle below the horizontal?
