[tex]\tt{\huge{\blue{Explanation:}}}[/tex]
The work done by gravity is given by
[tex]\boxed{W = mgh}[/tex]
where:
W = work
m = mass
g = acceleration due to gravity = 9.8 m/s²
h = height
[tex]\tt{\huge{\red{Solution:}}}[/tex]
Solving for the work
W = mgh
W = (0.8 kg)(9.8 m/s²)(10 m)
[tex]\boxed{W = \text{78.4 J}}[/tex]
Therefore, the work done is 78.4 J.
