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.
