To raise a 0.48-kg box from a shelf, 6 J of work is done. How far was the box lifted from the shelf? Round your answer to the nearest tenth.

The height through which the box was raised is 1.3 m.

Explanation:

Given;

mass of the box, m = 0.48 kg

work done in raising the box, W = 6 J

The work done in raising the box is calculated by work-energy theory; the work done in raising the box is equal to gravitational potential energy of the box due to the height it was raised.

W = P.E = mgh

where;

h is the height through which the box was raised

g is acceleration due to gravity = 9.8 m/s²

Therefore,  the height through which the box was raised is 1.3 m.

what question you dont ask a question

explanation:

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
