Let both the balls have the same mass equals to m.
Let 
and 
be the speed of the ball1 and the ball2 respectively, such that
Assuming that both the balls are at the same level with respect to the ground, so let h be the height from the ground.
The total energy of ball1= Kinetic energy of ball1 + Potential energy of ball1. The Kinetic energy of any object moving with speed, 
, is 
and the potential energy is due to the change in height is 
[where 
is the acceleration due to gravity]
So, the total energy of ball1,
and the total energy of ball1,
.
Here, the potential energy for both the balls are the same, but the kinetic energy of the ball1 is higher the ball2 as the ball1 have the higher speed, refer equation (i)
So, 
Now, from equations (ii) and (iii)
The total energy of ball1 hi higher than the total energy of ball2.
Okay! Thank you for this knowledge

4. c. 310 BCE - c. 230 BCE
Aristarchus of Samos. A Greek astronomer and mathematician
5. 384 BCE - 322 BCE
Aristotle Era.
6. c. 571 BCE - c. 497 BCE
Pythagoras of Samos lived during this era.
7. 585 BCE
Media and Lydia went into battle and broke off immediately as a result an entire eclipse of the sun which occurred causing the two armies to create peace. The eclipse was already predicted by Thales of Miletus.
8. 585 BCE
Thales of Miletus lived during now.
Explanation:
Ancient Greeks were some of the first people known to study the sky and understand what astronomy really entails. They discovered the Earth was spherical in shape and went ahead to devise a means to measure its size. They also were the ones who created the idea of a geocentric solar system, which was incorrect, But assisted us in understanding the universe for over hundreds of years.
