A big box of sausages (30 kg) is 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 against gravity?

Work done to lift the box is 515.03 J

Explanation:

By work energy theorem we know that work done by all forces is equal to change in kinetic energy

So we have

so we have

so we have

trig 15.3 cos

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
