A person lifts a 3.7 kg cement block a vertical distance of 1.18 m and then carries the block horizontally a distance of 7.80 m.

(a) How much work is done by the person in the process?
J

(b) How much work is done by gravity in the process?
J

w=fd?

OK. How much work then in lifting?

How much in carrying?
 
im not sure how to find that
 
got it. thanks
