Answer

Explanation:

Step1: Identify forces

The applied force $F_{applied}=35.0$ N and the frictional force $F_{friction}=2.90$ N act in opposite directions.

Step2: Calculate net - force

The net force $F_{net}$ is given by the difference between the applied force and the frictional force. Using the formula $F_{net}=F_{applied}-F_{friction}$. Substitute the values: $F_{net}=35.0 - 2.90$. $F_{net}=32.1$ N

Answer:

B. 32.1 newtons
