The amount of energy it takes to run a race is most likely to be a function of the; D: Length of the Race
We want to basically find the factor that influences the amount of energy expended by a sprinter.
Now, formula for potential energy is;
P = mgd
where;
m is mass
g is acceleration due to gravity
d is distance covered
Now, the only option that falls into the input that affects energy expended is the distance covered. This is true because the more the distance covered, the higher the energy expended.
