content: For those who don't ski, she isn't doing anything at all to slow down, and doesn't appear to know how.  A beginner would move the backs of their skis outwards, making a wider wedge, in order to slow down.  A non beginner would change direction so they aren't going straight down.    Also, her center of balance is completely off.  She is leaning backwards in the skis.  Knees should be bent forwards, with the center of balance over the bindings.  Then shift balance left or right in order to turn.  Since she is leaning backwards, any shift in balance would throw her off completely, and cause a fall.  (In this case, a fall may not be a bad idea.  It's the easiest way to stop without running into anything.)
