A 75 kg skydiver in free fall is subjected to a crosswind exerting a force of
60 N and to a vertical air resistance force of 100 N. Calculate the resultant
force acting on the skydiver [6 marks] and his angle of fall (relative to
vertical) [6 marks].

  • physics -

    Thee forces act on the skydiver:
    Weight = M g = 735 N down
    Vertical air resistance = 100 N up
    (Net vertical force = 635 N down)
    Horizontal wind force = 60 N
    Resultant force = sqrt[(635^2 + 60^2] = 637.8 N

    Ultimately, the skydiver will fall in the direction of the resultant force, arctan(60/635) = 5.4 degrees from vertical
