Question

newtons first law quick check
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)
more information is needed.
the book will move to the right.
the book will stay stationary.
the book will move to the left.

Explanation:

Step1: Calculate the net force

The pushing force \(F_{push}=7N\) (to the right) and the frictional force \(F_{friction} = 3N\) (to the left). The net force \(F_{net}\) is given by \(F_{net}=F_{push}-F_{friction}\) (since they are in opposite directions).

$$F_{net}=7N - 3N=4N$$

Step2: Determine the direction of motion

Since \(F_{net}=4N>0\) and the positive direction is taken as the direction of the pushing force (to the right), the book will move in the direction of the net force.

Answer:

The book will move to the right.
