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 chord length
See attachment for illustration
First, calculate distance AX using Pythagoras theorem.
This gives:
Collect like terms
Take square roots of both sides
AB is then calculated as:
Where:
So:
