Answer:
Hey
(note you have forgotten your diagram so this may not be what you where hoping for.)
The important discovery that galilao made was that he proved that <em><u>all objects no matter their mass fall at the same rate.</u></em>
That is to say that a bowling ball falls at the same rate as a truck.
An object in motion eventually stops because of friction.
<h3>What is Newton’s first law of motion?</h3>
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or continue its moving in a straight line at constant speed unless force is applied on it.
So we can conclude that An object in motion eventually stops is the correct answer.

To solve the problem it is necessary to apply energy conservation.
By definition we know that kinetic energy is equal to potential energy, therefore
PE = KE
Where,
m = mass
g = gravitaty constat
v = velocity
h = height
Re-arrange to find h,
Replacing with our values
Therefore the correct answer is C.
