How Micheal Jordan Jumps so high

Micheal Jordan didn't get the nickname "Air Jordan" for nothing. He is known for his ability to jump really high in order to perform epic slam dunks. How does he do this?

Micheal Jordan stands 1.98 m tall and has a wingspan of 2.13 m. A basketball hoop is 3.05 m high; therefore, he has to jump about .16 m above the ground for his hand to reach the rim. Jordan is most famous for his dunk from the foul line which is 4.57 m from the basket. In order for him to successfully complete this projectile, he must jump with an initial velocity of 25.31 m/s from the ground; 1.77 m/s in the vertical direction and 25.25 m/s in the horizontal direction. 

In order to produce this velocity he must push of from the floor with a force of 1454 N if he pushes off of the ground for .2 seconds.

Sense check.  Usain Bolt max speed is 12.27m/s.  How is Jordan able to obtain horizontal velocity around 25m/s???

That's an initial velocity from a jump.  Usain Bolt is looking at his whole body running where 12.27 m/s is a sustained speed.
