A skier (weighing 502.4 N) starts at the top of a very large frictionless snowball with an initial speed of 1'? , where g is the acceleration due to gravity and R is the radius of the snowball , and skis straight down the side. You can treat the skier as a point mass in this problem. Calculate the normal reaction (in Newtons) on the skier from the ice when the angle a (as shown in the figure) is 30. [You can assume that she has not lost contact with the ice yet] / f___--_ I \\ A) 187 B) A numerical answer is not possible without knowing the value of R 0) None of these D) 133 E) 200
