consider a box of 2.5 kg dragged along a horizontal floor by a horizontal force F= 16.0 N through a distance of 12.0 m. Find the work done on the box by the force of gravity?
Homework Answers
workdone on the box by the force of gravity is
W = F d cos theta
= mg d cos theta
= 2.5 (9.8) (12) cos 90
= 0
