The box is sitting on the floor of an elevator. The elevator is slowing down moving upward. The magnitude of the normal force on the box is:

Sagot :

Answer:

The magnitude of the normal force on the box is N= m*g + W

Explanation:

According to Newton's Second law and normal force.

  • The resultant of the forces acting on the person must be equal to the product between the mass and the acceleration a of the person itself.

so with the help of Newton's second law

we can write the equation for force:

F = ma

Since,

box is sitting on floor of an elevator.

there are two forces acting on this box:

  1. W due to it's weight (downward)
  2. N due to the normal force of the floor against the body (upward).

So we can rewrite the previous equation as,

N - W = F

N - W = ma

hence,

N=m*a + W

this is the The magnitude of the normal force on the box.
