Question

A teacher pushed a 98 newton desk across a floor for a distance of 5 meters. She exerted a horizontal force
of 20 newtons. How much work was done?

Answer 1

the work done to move the across the floor is equal to

W = Fd

where is the horizontal force applied to move the desk on the floor and is the distance covered by desk

where

F= 20

d = 5

so according to formula

W= Fd = (20N) (5m)

= 100 J

Hope this helps you buddy ☺️☺️✌️✌️❤️❤️
