friction graphs
17 fill in the blank 2 points
use the given information & the graph shown in this section to answer the following question. a box with a mass of 18.0 kg is being pushed on a level surface with a horizontally applied force.
if the box is at rest and the applied force is 35.0n, how much will the magnitude of the friction force be? type your answer.

Explanation:

Step1: Understand static - friction concept

When an object is at rest, the static - friction force \(f_s\) balances the applied force \(F_{app}\) up to the maximum static - friction force.

Step2: Apply force - balance for stationary object

Since the box is at rest, according to Newton's first law (\(\sum F = 0\) in the horizontal direction), the magnitude of the friction force \(f\) is equal to the magnitude of the applied force. Given \(F_{app}=35.0N\), then \(f = 35.0N\).

Answer:

35.0 N
