The potential energy of the lemming is 1.53 J

Explanation:

The potential energy (PE) of an object is the energy possessed by the object due to its position in the Earth's gravitational field, and it is given by:

[tex]PE=mgh[/tex]

where:

m is the mass of the object

[tex]g=9.8 m/s^2[/tex] is the acceleration of gravity

h is the height of the object relative to the ground

In this problem:

m = 0.0780 kg is the mass of the lemming

We want to find the potential energy when the height is

h = 2.00 m

Therefore, we find:

[tex]PE=(0.0780)(9.8)(2.00)=1.53 J[/tex]
