A skier skis from rest from a vertical height h1 = 19.1 m over two successively lower hills of vertical heights h2 = 15 m and h3 = 5.2 m. (Fig. 7-30). The summit of the third hill fits a circle of radius h3 centered at height 0 m. Friction with the snow and air resistance are negligible.
(b) Does the skier leave the surface at x3?
Yes/No
If not, what should h1 be so that she just leaves the surface at x3? If yes, find the maximum value of h1 at which the skier stays on. (Ignore the middle hill in this calculation.)
_________m
so the skier does leave the surface at X3 but i don't know why.
