Early one October, you go to a pumpkin patch to select your Halloween pumpkin. You lift the 2.8 kg pumpkin to a height of 1.4 m, then carry it 50.0 m (on level ground) to the check-out stand.
Calculate the work you do on the pumpkin as you lift it from the ground?
and How much work do you do on the pumpkin as you carry it from the field?

work= mgh
a)work=mgh so work=(3.4kg)(9.8m/s^2)(1.4)=47J
b.) work=Force x Distance x Cos(angle)
Work = (3.4kg)(9.8m/s^2)x Cos(90)
Work = 0J
Work = (3.4kg)(9.8m/s^2)x Cos(90)
Work = 0J
