Homework Statement
A carpenter is holding two tool boxes of mass 19kg and 21kg respectively. Calculate the work done to carry the tool boxes through a horizontal distance of 16m.
Homework Equations
W = mgh
The Attempt at a Solution
m = 21kg + 19kg
g = 9.81ms^-2
h = 0
W = (21 + 19)(9.81)(0)
W = 0J
Is this correct? And if this is correct, would you explain why it is 0J?
