this is drivnig me nuts I've doen eveyrthin gon the worksheet but this is a weird one
A unifrom rectangular marble slab is 3.4m long and 2.0m wide. It has a mass of 180KG. If it is originally lying on the flag ground, how much work is needed to stand it on end.
I know work = force X distance
and to get force i multiply 180X9.8 like I've doen in all the other questions
but what's teh distance here it rises, it ried phythagorean theorem to get the distance and all these weird aways
but the asnwer should be
3000 J
dont nkow what to do!
thanks
