Question
A 10kg box, initially at rest, moves along a frictionless horizontal surface. A horizontal force to the right is applied to the box. The magnitude of the force changes as a function of DISPLACEMENT (Ignore the picture, which says time- it should say position in meters.)
Rank the work done on the bo during each 2-meter interval indicated below and please eplain your reasoning.
A. 0 to 2 m B. 2 to 4 m C. 4 to 6 m D. 6 to 8 m F. 8 to 10 m (OR the work done on the box is the same but not zero, OR the work done on the box of each interval is 0, OR we cannot determine).
Force, N 3 h Time, s 10 8Explanation / Answer
As you are saying to ignore the given graph shown above,there is no given relation between the force and displacement.To find the ranking of work done we must have the variation of force with displacement either functional or graphical otherwise we can not find the ranking of work done in any ways
