Question

A book is sitting in a table. Jackie is pushing the book with a force of 9 N. If the force of friction is 4 N to the left, what is the net force

Answer 1

The net force is 5N

Step-by-step explanation:

A shown in the diagram,

we let P be the force Jackie applied and

`F_r`

be the frictional force.

To get the net force, we subtract the frictional force from the applied force.

This implies that,

`F_n= P-F_r`

`F_n= 9 - 4`

`F_n=5N`
