Answer: 176.4 Joules
Explanation: Potential energy of a body is defined as the energy possessed by virtue of position.
Potential energy
m = mass of the body = 6 kg
g = acceleration due to gravity =
h = height of body = 3 m
Potential energy
= 176.4Joules {}
Let's use the mirror equation to solve the problem:
where f is the focal length of the mirror,
the distance of the object from the mirror, and 
the distance of the image from the mirror.
For a concave mirror, for the sign convention f is considered to be positive. So we can solve the equation for by using the numbers given in the text of the problem:
Where the negative sign means that the image is virtual, so it is located behind the mirror, at 8.6 cm from the center of the mirror.
