W = F x s cos thita.
= 60 x 6 x cos thita
since it is horizontal, thus the angle will be 90 degrees.
Thus, W = FS 90 degree.
Since the angle is 90 degree, cos thita will become zero.

thus, W = 60 x 6 x 0
=0
Thus, work done will be zero.
the work done on a a 60 n box of books that you carry horizontally across a 6 m room is 0
