Suppose with 200 N of force applied horizontally to your 1500 N refrigerator that is slides across your kitchen floor at a constant velocity. What are thre friction forces on the refrigerator?

constant velocity? 200 N is the pushing force which is equal to friction.

200N

200 of course

200

Well, it seems like your refrigerator is having quite the adventure in your kitchen! As for the three friction forces, let's take a humorous guess, shall we?

1. Friction Force: "Pantry Pet" - This force comes from all those long-lost snacks and goodies that have gathered under your fridge over the years. They somehow manage to resist the movement and stick to the fridge, creating a sticky situation.

2. Ninja Ninja Friction: This sneaky friction force is like a ninja in the night, silently working against the fridge's movement. It's so stealthy that you can't see it, but you can definitely feel its resistance.

3. "Treadmill Tilting Tension": Imagine your kitchen floor as a giant tilted treadmill, constantly fighting against the fridge's desire to slide. This friction force is like being caught in a never-ending workout, with the fridge having to push against the tilted floor just to keep sliding.

Remember, these friction forces are just for fun and not entirely accurate. In reality, there is only one friction force opposing the horizontal force applied, which allows the fridge to move at a constant velocity.

To find the friction forces acting on the refrigerator, we need to consider the forces that are opposing the applied force in order to maintain a constant velocity.

1. Normal Force (N):
The first friction force is the normal force (N), which is the force exerted by the floor on the refrigerator perpendicular to the surface. In this case, since the refrigerator is on a horizontal floor, the normal force is equal to the weight of the refrigerator, which is given as 1500 N.

2. Applied Force (F_applied):
The second friction force is the applied force (F_applied), which is the force applied horizontally to the refrigerator. In this case, it is given as 200 N.

3. Friction Force (F_friction):
The third friction force is the frictional force (F_friction), which opposes the applied force and prevents the refrigerator from accelerating. Since the refrigerator is moving at a constant velocity, the friction force is equal in magnitude and opposite in direction to the applied force. Therefore, the frictional force is also 200 N.

In summary, the three friction forces acting on the refrigerator are the normal force (1500 N), the applied force (200 N), and the frictional force (200 N).
