Answer:
1.24 J
Explanation:
The work done by a force is given by
where
F is the magnitude of the force
d is the displacement
is the angle between the directions of F and d
In this problem,
F = 0.18 N is the average force exerted by the muscles
d = 6.9 m is the displacement
(we assume the direction of the force is parallel to the displacement)
Substituting,
Answer: The water and sun.

No. The correct answer is A.
The kinetic energy of any moving object is
(1/2) (mass) (speed²) .
For the object you described, that's
(1/2) (100 kg) (12.5 m/s)²
= (50 kg) (156.25 m²/s²)
= 7,812.5 joules
