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

Explanation

To solve the problem of determining the frictional force exerted on a wooden cabinet when a horizontal force of 200 N is applied to move it at a constant velocity, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Situation**: We have a wooden cabinet that is being pushed with a horizontal force of 200 N. It is moving at a constant velocity across the floor.

2. **Identify Key Concepts**: When an object moves at a constant velocity, it means that there is no net acceleration acting on it. According to Newton's first law of motion, if the velocity is constant, the forces acting on the object are balanced.
