Asked by Dalton

A bookshelf is at rest in a room. A force of 35.0 newtons is applied to a bookshelf. If the floor imparts a frictional force of 2.90 newtons, what is the net force acting on the bookshelf?
37.9 newtons
32.1 newtons
33.1 newtons
35.0 newtons
50.5 newtons
Answered by Gavin
It has to be 37.9 or 32.1

The others are wrong I think.
Answered by Damon
The net horizontal force is 35 -2.9 = 32.1 N
