Answer:
Point x.
Step-by-step explanation:
The potential energy of an object is simply defined as the energy stored in an object by virtue of its location. Mathematically, it is expressed as:
PE = mgh
Where
PE => is the potential energy
m => is the mass of the object
g => is acceleration due to gravity
h => is the height
From the formula i.e PE = mgh, we can see that the potential energy (PE) is directly proportional to the height (h).
This simply indicates that as the height increases, the potential energy will increase and as the height decreases, the potential energy will also decrease.
Now, let us consider the question given above.
Point x indicates the greatest height attained by the ball. Therefore, the ball will have it's greatest potential energy at point x.
