Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_56

2/56 The center of mass \(G\) of a high jumper follows the trajectory shown. Determine the component \(v_0\), measured in the vertical plane of the figure, of his takeoff velocity and angle \(\theta\) 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?)
