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.
