The altitude or height of the pole vaulter as she crosses the bar is 4.04 m.
<h3>What is the height of the pole vaulter?</h3>
The height of the pole vaulter is determined from the change in kinetic energy which is equal to the potential energy at that height.
- Potential energy = Change in kinetic energy
h = (v - u)²/2g
h = (10 - 1.1)²/2 * 9.8
h = 4.04 m.
In conclusion, the height is determined from the potential energy at that height.
