How much work is done on a a 60 n box of books that you carry horizontally across a 6 m room?

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
