A skier starts at the top of a 60? slope, 25 m above the ground, as shown at right. At the bottom, a circular arc carries them through a 90? turn and they lunch of a 3.0 m height ramp. Assume all surfaces are frictionless.

[10 points] A skier starts at the top of a 60 slope, 25 m above the ground, as shown at right. At the bottom, a circular arc carries them through a 90 turn and they launch off a 3.0 m hight ramp. Assume all surfaces are frictionless. 25 m 2017 Eucation in 60 90 13.0 m (a) What is the skier's speed the instant they leave the ramp? Hint: energy conservation. (b) How far horizontally is the skier's touchdown point from the end of the ramp? Hint: projectile motion; the skier's launch angle is 30. (c) Prove that the skier's launch angle is 30. You will need to show a complete diagram simply stating it is 30 because of geometry" or "similar triangles" is not sufficient.
