In 1988, Greg Louganis of the United States, arguably the greatest Olympic diver in history, cracked his head on the springboard while attempting a reverse 2.5 pike. After receiving stitches, Louganis won gold medal in diving.
Greg Louganis jumping from the spring board exhibits somersaults in air before touching the water surface. After leaving the spring board, he curls his body by rolling the arms and the legs inwards. Due to this, his moment of inertia decreases and he spins in mid air with large angular speed. As he is about to touch the water surface, he stretches out his limbs. This increases his moment of inertia and he enters the water at a gentle speed.Do check out chapter wise Physics Questions prepared by Entrancei.
