2.) A horizontal force of 100 N is required to push a piece of furnisher across a floor at a constant velocity.
(a.) What is the net force acting on the furniture?
Applied force minus friction force, if the floor is level.
To find the net force acting on the furniture, we need to understand the concept of equilibrium. When an object is moving at a constant velocity, it means that the net force acting on it is zero. In this case, since the furniture is being pushed with a constant velocity, the net force acting on it must also be zero.
The force required to push the furniture horizontally is given as 100 N. Since there is no vertical force mentioned, we can assume that the furniture is on a horizontal surface, and there is no additional force acting in the vertical direction.
Therefore, in this scenario, the net force acting on the furniture is zero N.
