Always start with the definition:
w = a b F ( x ) d x
Sometimes, the simple problems are the hardest because it looks too easy so we tend to add unnecessary things. Since this is a vertical lift, we are dealing with gravity which is 9.8 m s 2 . So,
F ( x ) = 9.8 m s 2 40 k g = 392 N
Remember that work is force times distance. We have force which is just a constant function. And we have distance which is dx. The tendency is to add an x into F(x)=392N , but that would be incorrect. Now, let's put it together:
a=0
b=1.5
W = 0 1.5 392 d x
= 392 x | 0 1.5
=588J
