CP A skier starts at the top of a very large, frictionless snowball, with a very small initial speed, and skis straight down the side (Fig. P7.55). At what point does she lose contact with the snowball and fly off at a tangent? That is, at the instant she loses contact with the snowball, what angle ? does a radial line from the center of the snowball to the skier make with the vertical?
Solution 63P Step 1 of 3: a) Loses contact implies n 0 y = r 1 y = R cos 2
