Answer:
846.72 J
Explanation:
Given that,
The mass of the package = 36 kg
It is raised through a vertical height of 2.4 m.
Initial potential energy of the package will be 0 as it was at ground.
The change in gravitational potential energy is given by :
[tex]\Delta E=mgh\\\\=36\times 9.8\times 2.4\\\\=846.72\ J[/tex]
Hence, the change in gravitational potential energy is 846.72 J.
