The potential energy of an object is given by
[tex]\boxed{PE = mgh}[/tex]
where:
PE = potential energy
m = mass
g = acceleration due to gravity = 9.8 m/s²
h = height
[tex]\tt{\huge{\red{Solution:}}}[/tex]
Solving for PE
Note: 458 g = 0.458 kg
PE = mgh
PE = (0.458 kg)(9.8 m/s²)(2 m)
[tex]\boxed{PE = \text{8.98 J}}[/tex]
Therefore, the potential energy of the book is 8.98 J.
