Answer:
top of the highest hill
Explanation:
The potential energy of an object is given by
[tex]U=mgh[/tex]
where,
m = Mass of the object
g = Acceleration due to gravity
h = Perpendicular distance from the ground.
It can be seen that the potential energy is proportional to height
[tex]U\propto h[/tex]
Here, the car will have maximum potential energy when it is at the maximum distance from the ground.
Hence, the car will be at the top of the highest hill
