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?

I do not understand the direction of the 35N force.

To find the net force acting on the bookshelf, we need to calculate the difference between the applied force and the frictional force.

The applied force is given as 35.0 newtons, and the frictional force is given as 2.90 newtons. Since the bookshelf is at rest, the net force acting on it should be zero.

Using this information, we can calculate the net force as follows:

Net force = Applied force - Frictional force

Net force = 35.0 N - 2.90 N

Net force = 32.1 N

Therefore, the net force acting on the bookshelf is 32.1 newtons.
