Friction in an Elevator you are riding in an elevator on the way to the 181h floor
Question:
Friction in an Elevator you are riding in an elevator on the way to the 181h floor of your dormitory. The elevator is accelerating upward with a = 1.90 mls2, beside you is 1he box containing your new computer; the box and its contents have a total mass of 28.0 kg. While the elevator is accelerating upward, you push horizontally on the box to slide it at constant speed toward the elevator door. If the coefficient of kinetic friction between the box and the elevator floor is μk = 0.32, what magnitude of force must you apply?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
