A skier starts at the top of a very large, frictionless snowball, with a very small initial speed, and skis straight down 1he side (Fig. 7.38). At what point does she lose contact with the snowball and By off at a tangent? That is, at the instant she loses contact with the snowball, what angle a does a radial line from the center of the snowball to 1he skier make with the vertical? |
