Answer:
A
Explanation:
It would not be C because prokaryotic cells don't have a nucleus. And if you're looking for a body in the cell that controls the nutrients and water it would be A.
The kinetic energy possessed by the man is 517.5 Joules.
<u>Given the following data:</u>
To find the kinetic energy of the man:
Kinetic energy is an energy that is possessed by a physical object or body due to its motion.
Mathematically, kinetic energy is calculated by using the formula;

<u>Where:</u>
- K.E is the kinetic energy.
- M is the mass of an object.
- V is the velocity of an object.
Substituting the given values, we have;
×
× 
× 
<em>Kinetic energy = 517.5 Joules.</em>
Therefore, the kinetic energy possessed by the man is 517.5 Joules.
