A 57.0 kg pole vaulter running at 9.00 m/s vaults over the bar.

The acceleration of gravity is 9.81 m/s
I got 4.28 and I don't know what i did wrong

.

If the vaulter’s horizontal component of velocity over the bar is 1.7 m/s and air resistance

is disregarded, how high is the jump?

Answer in units of m.
