----------
Weiping lifts a rock with a weight of 1.0 N through a height
of 1.0 m, and then lowers it back down to the starting point. Bubba
pushes a table 1.0 m across the
oor at constant speed, requiring
a force of 1.0 N, and then pushes it back to where it started. (a)
Compare the total work done by Weiping and Bubba.
I think Bubba did the greater work because he was pushing the object at a constant velocity where as weiping only lifted it . Is my assumption correct?
