1. The problem statement, all variables and given/known data A 70-kg woman skies down a slope and then encounters the top of a huge snowball of radius 5 m while she is moving at 3 m/s. She continues over the surface of the "ball" until she ultimately parts company from the "ball" at an angle (alpha) which is measured by the radial line to her from the vertical. Consider the snow and ice of the "ball" to be frictionless. Employing both energy considerations and Newton's 2nd law, determine the height above the ground and the angle at which she leaves the "ball". 2. Relevant equations F=ma. 3. The attempt at a solution I don't really know where to begin. Please help!
