The potential energy is 4.10 J

Explanation:

The potential energy of a body is given by

$U=mgh$

where

m is the mass of the object

g is the acceleration of gravity

h is the height of the object relative to the ground

For the lemming in this problem we have

m = 0.078 kg is its mass

h = 5.36 m is the height above the ground

$g=9.8 m/s^2$ is the acceleration of gravity

Solving the equation,

$U=(0.078)(9.8)(5.36)=4.10 J$
