A skier is accelerating down a 30 degree hill at 3.80 m/s^2. Draw a convenient XY coordinate system, then determine:
a) What is the vertical component of her acceleration?
b) How long does it take her to reach the bottom, assuming she starts from rest and accelerates at a constant rate, if her elevation change is 355m?
This solution is provided in 296 words in an attached .doc file. It uses a diagrams to further understanding of the problem and equations to find acceleration and time.
