Answer :
Newton horizontal force is exerted upon a 3.1-kg box to move it across a level surface at a constant velocity of 1.4 m/s. The force of friction encountered by the box is 4.84N.
Explain force of friction?
Friction is a force that resists the movement of two objects that are in contact with each other. Friction is a force that can be beneficial or detrimental depending on the situation.
- In most cases, friction is beneficial because it allows us to move and use things more easily. For example, friction allows us to walk on a surface without slipping, and it also helps us grip objects.
- Without friction, we would be unable to perform actions like writing or holding a cup of coffee.
- When two surfaces come into contact, friction is produced. The amount of friction between two surfaces is determined by the type of surface, the amount of force applied, and the amount of contact between the two surfaces.
- The rougher the surface, the more friction will be generated. The more force applied, the stronger the friction will be. Finally, the larger the area of contact between the two surfaces, the greater the friction will be.
- Friction can be beneficial or detrimental, depending on the situation. In some cases, friction can be beneficial and help us move and use things more easily.
- In other cases, it can be detrimental and cause unwanted resistance. It is important to consider the effects of friction when designing objects and performing activities.
Now,
F = ma
F = 3.1 kg * 1.4 m/s^2
F = 4.84 N
