Astuntman jumps from the roof of a building to the safety net below. how far has the stuntman fallen after 2 seconds

-- Gravity adds 9.8 m/s to his falling speed every second.
   After 2 seconds, his falling speed is (2 x 9.8) = 19.6 m/s .

-- His initial speed ... as he steps off the roof ... was zero.
   His final speed, at the safety net, is  19.6 m/s.
   His average speed all the way down is  (1/2) (0 + 19.6) = 9.8 m/s .

-- Falling for 2 seconds at an average speed of 9.8 m/s,
   he covers a vertical distance of (2 x 9.8) = 19.6 meters.

Cool discovery:
After falling from rest for 2 seconds, the speed is the same number as
the acceleration, and the distance fallen is double the acceleration. 
In ANY system of units.
(But the units of the three numbers are different.)

Football was the fourth deadliest sport with a fatality rate of .81 per 100,000 participants. cheerleading, which has been shown to be the most dangerous activity based on injury data, was not included in the study because it was not classified as a sport.this is my answer because it didn’t give me any sports
