d = r = 31.7m = Vertical distance
traveled.
V^2 = Vo^2 + 2g*d.
V^2 = 0 + 19.6*31.7 = 621.32,
V = 24.9 m/s.
A skier starts at rest and glides (without friction) directly down the fall line from the highest point of a giant snowball with a radius of r=31.7 m . The skier can be observed as a point mass and the air resistance is negligible.
What speed v does the skier have when she loses contact with the snowball?
