3) The figure below illustrates a skier who is skiing on a large frictionless spherical ball of snow. The skiercan be treated as a point-like object. The skier starts at the top of the ball with very little speed and picks upspeed while traveling along the surface of the snow. During this time, the only forces acting on the skier arethe gravitational force applied by the Earth and the normal force applied by the snow. At the moment theradial line extending from the skier to the center of the ball defines an angle a with respect to a vertical line,the skier is about to lose contact with the ball. Determine the value of a. Note: Use work and energy methods to solve these problems.

Let m be defined as the mass of the skier, and R be defined as the radius of the spherical ball. Let…
