The center of mass G of a high jumper follows the trajectory shown. Determine the component vo, measured in the vertical plane of the figure, of his takeoff velocity and angle 0 if the apex of the trajectory just clears the bar at A. (In general, must the mass center G of the jumper clear the bar during a successful jump?)
