The correct option is;
c. He conducted experiments with balls and inclined planes
Explanation:
The inclined plane experiment conducted by Galileo Galilei was one of his most important experiments.
The experiment consisted of a grooved board with which a small metal ball is rolled down in, so as to analyze the held Aristotelian ideas about motion.
In the experiment, the focus was on acceleration, a concept that the previously held ideas about motion
Answer:
22050 J
Explanation:
Given Mass of the ball, m = 4.5 Kg
Height, h =500 m
Acceleration due to gravity, 
To calculate the potential energy we use formula,

Substituting the given values, we get
PE = 4.5× 9.8×500
=22050 J
