Question

An 800 N table is slid across the kitchen floor by pushing with a force of 100 N. If the table moves at a constant speed, what is the friction force with the floor?

A. 100 N
B. 8 N
C. 800 N
D. over 800 N

Answer 1

A. 100 N

Step-by-step explanation:

Given

Table = 800N

Pushing Force = 100N

Required

Determine the friction force with the floor

From the question, we understand that the table moves at a constant speed.

In this kind of situation, the friction force equals to the pushing force.

Hence:

Friction Force = Pushing Force

Friction Force = 100N
