Given:
Mass of object = 2 kg
At point E, the gravitational potential energy is 0.
Let's find the maximum height the object will reach above point E.
[tex]PE=mgh[/tex]
Where:
m is the mass
g is acceleration due to gravity
h is the height.
The maximum height the object will reach above point E will be the height at Point C if the restriction is to the given points.
Point C is 20 m above the ground.
Therefore, the maximum height that it reaches above point E is 20 m.
ANSWER:
20 m.
