Question

(a) The mass of the package is 36 kg.

Calculate the increase in the gravitational potential energy (g.p.e.) of the package when it is

raised through a vertical height of 2.4 m

HELP

Answer 1

846.72 J

Step-by-step 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 :

`\Delta E=mgh\\\\=36* 9.8* 2.4\\\\=846.72\ J`

Hence, the change in gravitational potential energy is 846.72 J.
