Question

using a horizontal force of 200 Newton we tend to move a wooden cabinet across the floor of constant velocity what is the friction force that will be exerted on the cabinet

Answer 1

It moves with constant velocity,

So no acceleration is there

That means net force is Zero

So friction = 200N in the direction opposite to motion

Answer 2

Answer:

Since the wooden cabinet is to be moved at constant velocity, this means that the whole force of 200 N will be used to overcome the force of friction. Thus, the force of friction exerted on the cabinet will be equal to the force applied, which is 200 N.
