Answer:
490 J
Explanation:
The work done to lift an object is equal to its increase in gravitational potential energy, therefore
[tex]W=mgh[/tex]
where
m is the mass of the object
g = 9.8 m/s^2 is the acceleration of gravity
h is the increase in height of the object
In this problem,
m= 5 kg
h = 10 m
Therefore, the work done is
[tex]W=(5 kg)(9.8 m/s^2)(10 m)=490 J[/tex]
