Because the force acts perpendicular to the direction of displacement
Now W=F. S. cos(90*)
=F.S.0 [cos 90* = 0]
So, W=0

thats wrong
Sorry
da mm it.
would someone xplain
yes because the suitcase has not come in motion thats it
the suitcase is on its head n he is walking..how is that possible that displacement has not ocurred
No displacement has occurred but you are applying force towards the top but displacement is horizontally and thus work done is 0
arey the man is in motion but the suitcase is not that is on its head
think practicallyy
