On June 9, 1988, Sergei Bubka broke the world pole-vaulting record for the 8th time in four years by attaining a height of 6.14 m.

How long was Bubka in the air for this record setting vault?

• Physics -

Not possible. On the uplift portion of a pole vault, there is no "initial vertical velocity", as it is the spring action of the pole which does the lift, there is a force vertical nearly all the way upwards.

However, you can figure the time it took to fall if you wish.
