a. What are the (x,y) components of the initial velocity? m/s Vix = 4 ymax yi m X = b. What is Ay, the height above the end of the ramp? What is ymax? Ay= Viy Seconds 2. A skier travels down a slope, which turns up at the bottom, launching the skier at an angle = 53°above the horizontal. The skier leaves the end of the ramp with an initial speed of 35 m/s. The end of the ski ramp is y₁ = 10 m above the ground. Ymax F m m/s. c. Use the quadratic formula to determine how much time the skier is in the air? m d. How far from the end of the ramp, horizontally, does the skier hit the ground?
