Abig box of sausages (30 kg) are lifted from the ground to the top shelf of the freezer. if the box is lifted at a constant speed, a distance of 1.75 m, what work is done by gravity?

The work done by gravity moving the box up is -514.5 Joules.

Explanation:

The gravity acts in the direction of the displacement, which in this case is negative (ground - top shelf), and so the resulting work is negative. The work is calculated as:

The work done by gravity moving the box up is -514.5 Joules.

answer; equivalent to a one(1) horsepower motor;

thermal energy is the answer
