Kinetic energy is defined as :
For this case, the first thing you should know is that the length of a football field is around 100 meters.
We must then look for a measure close to this value.

Applying the conversion we have:
Therefore, the measure closest to a soccer field is:
1000 dm
Answer:
The length of a football field is closest to:
(2) 1000 dm
