The sum of the ball's kinetic energy and potential energy remains the same. as the ball rolls from point A to E.( if there is no friction between the ball and the ground).
based on the law of mechanical energy's conservation, the sum of both kinetic and potential energies i.e. the total amount of mechanical energy remain conserved even in the absence of dissipative forces ( friction or air resistance) in a bound system.
the kinetic energy is when ball goes downward but potential energy decreases and reverse happens when ball goes up. but in these case, the sum energy would be constant one.
The ball would not change the energy.

Answer:
Step-by-step explanation:
Given that:
Number of seats sold is 180 with ticket price $200.
Number of seats decreases by one when the ticket price is increased by $3.
To find:
The formula for the number of seats sold (S) when the ticket price is P dollars.
Solution:
It is linear dependency of number of seats sold, S on ticket price, P.
It can be written as:
Where 
is the constant of proportionality and
is a constant.
Now, putting the given values:
...... (2)
Subtracting (1) from (2):
Putting the value in (1):
Therefore the equation becomes:
