A porter pulls a 10-kg luggage along a level road for 5 m by exerting force of 20N at an angle of 30 degrees with the hrizontal shoulder thr

☛ BTW, I'm interpreting the nub of the question to be: how much work is done in lifting the luggage onto his shoulder?

This is some sort of trick question, is it? Where the only relevant motion is:

" Through a vertical distance of 1.5 m "

You have lost some essential dialog from the question specification, too.

So the answer is just weight x 1.5m  🎅🎅
