Consider a situation where you carry a 20-N box up a flight of stairs, raising its elevation by 5 m.
-The work you do is 4 J.

Question

Quizplus · Accepted Answer

The work done in lifting a box to a height h is given by W = mgh where m is the mass of the box, g is the acceleration due to gravity, and h is the height. Therefore, W = (20 N) * (9.81 m/s^2) * (5 m) = 981 J. Since the given work is only 4 J, it is not possible to raise the box to a height of 5 m with that amount of work.
