Question 10
Using a horizontal force of 200 N, we intend to move a wooden cabinet across a floor at a constant velocity. What is the friction force that will be exerted on the cabinet?

Open in App

Solution

The cabinet will move with constant velocity only when the net force on it is zero. Therefore, the force of friction on the cabinet = 200 N, in a direction opposite to the direction of motion of the cabinet.
