The specialty of an athlete on the women's track team is the pole vault. She has a mass of 58 kg and her approach speed is 9.3 m/s. When she is directly above the bar, her speed is 1.4 m/s. Neglecting air resistance and any energy absorbed by the pole, determine the amount(in m) she has raised herself as she crosses the bar.
