Question

Calculate the work done by a man holding suitcase weighing 5kg in his hand

Answer 1

the work done by a man holding suitcase weighing 5kg in his hand is zero...becoz the body is in perpendicular state.

Answer 2

Work = 0

as there is no work done work is done only when an object is lifted to a height

or is moved along a distance. Neither of these is done so no work done
