A force of 80 N is applied by a janitor on the handle of a mop held at 40° with the floor. How much force is pushing the mop across the floor?

1 Answer

#61.28355544951824\ N#

Explanation:

The cosine component of applied force #F=80\ N#, at angle #\theta=40^\circ# with the floor, will push the mop across the floor which is given as

#F\cos\theta=80\cos40^\circ=61.28355544951824\ N#
