I think I have both answers, but I really need (b) explained. You go to a pumpkin patch to select your Halloween pumpkin. You lift the 3.2kg pumpkin to a height of 1.2 m, then carry it 50.0 m on level ground to the checkout stand.

(a) Calculate the work you do on the pumpkin as you lift it from the ground, and
(b) How much work do you do on the pumpkin as you carry it from the field.
