Question

a pushing force of 7 n to the right is applied to a book on a table. a frictional force of 3 n is applied in the opposite direction. in which direction will the book move? (1 point)
the book will move to the left.
the book will stay stationary.
the book will move to the right.
more information is needed.

Explanation:

Step1: Calculate the net force

The pushing force \(F_{push}=7N\) (right - positive direction), frictional force \(F_{friction} = 3N\) (left - negative direction). Net force \(F_{net}=F_{push}+(-F_{friction})\).

$$F_{net}=7 - 3$$

Step2: Determine the direction

$$F_{net}=4N$$

(positive value means direction is to the right)

Answer:

The book will move to the right.
