yeah mike is right….
there is no way someone should jump 7.56m running 10.5m/s…
i have somewhere a chart where this has been figured out. I am not sure where but i will look.
But 10.5 m/s with a take off angle of 21 degrees will be over 8 metres.
and just to add, when i jumped 7.54m i wasnt running anywhere near 10.5 m/s . . .last year i was closer to that speed, however fouls and bad landings created many problems…
