How much work is done by carrying a 15 kg box across a 15-meter hallway?

Sagot :

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The work done by an object exerting a force F at a distance d is given by

[tex]\boxed{W = Fd}[/tex]

where:

W = work

F = force

d = distance

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for the work

W = Fd

W = (0 N)(25 m)

[tex]\boxed{W = \text{0 J}}[/tex]

Therefore, the work done is 0 J.

-----------------------------------------------------

Note:

The work done is 0 because the force (direction is upward) is perpendicular to the displacement. In order for the work to be done, the force must be parallel to the displacement.
