China diving dream team made brilliant achievements in the 2008 Beijing Olympic Games. According to scientific calculation, divers are in poor health when they are training in10m platform diving.

Solution: (1) Let the parabolic equation be y=,

Then you can know,

If the image must pass (0,0) and (2,-10), there will be,

By contrast,

Get a solution,

∴ 。

(2) When the horizontal distance between athletes in the air and the pool edge is 100 meters,

That is, when x=, y=,

So at this time, the distance between the athlete and the water surface is zero, so there will be mistakes in this diving.

(3) Assuming that the diving posture is adjusted successfully, the horizontal distance from the pool edge is m (m(m>2)).

So, okay,

Therefore, the maximum horizontal distance between athletes and swimming pool is 100 meters.
