Answer:
The potential energy of the ball having 2kg mass would be J
Step-by-step explanation:
I am assuming the ball has a mass of 2 kg, as you have not mentioned the mass of a ball.
Considering the formula for calculating the gravitational potential energy
As
kg
Acceleration of gravity = g = 9.8
As the ball is on the height = h = 20 meters
So,
J
Therefore, the potential energy of the ball = J

The general equation for a circle is:
where (h,k) is center of circle
r = radius
For this example, from the graph you see the center is at (0,-3) and radius is 2.
h = 0, k = -3, r = 2
