Transcribed Image Text:Problem 2.103 An alpine ski jumper can fly distances in excess of 100 m by using his or her body and skis as a "wing" and therefore, taking advantage of acrodynamic effects. With this in mind and assuming that a ski jumper could survive the jump, determine the distice the jumper could "fly" without aerodynamic effects, i.e., if the jumper were in free fall after clearing the ramp. For the purpose of your calculation, use the following typical data: a = 11° (slope of ramp at takeoff point A). 8 = 36° (average slope of the hi) 3m (height of takeoff point with respect to the hil 86 km/h (speed at A), h = Finally, for simplicity, let the jump distance be the distance between the takeoff point and the landing point B. Figure P2.103 "On March 20, 2005, using the very large ski ramp at Planica, Slovenia. Bjorn Einar Romaren of Nor set the world record by flying a distance of 239 m. While the given average slope of the landing hill is accurate, you should know that, according to regu lations, the landing hill must have a curved profile. Here, we have chosen to use a landing hill with a constant slope of 36° to simplify the problem.
