A50- kg pole vaulter running ar 10m/s vaults over the bar. her
speed when she is above the bar is 1.0 m/s. neglect airresistance,
as well as any energy absorbed by the pole, anddetermine her
altitude ads she crosses the bar.

5.05 m

Explanation:

Given:

According to the work-energy theorem, work done by the gravitational force will be equal to the kinetic energy change in the vaulter.

Hence, the height of the vaulter is 5.05 m.
