Question

A box of books with mass 43 kgkg rests on the level floor of the campus bookstore. The floor is freshly waxed and has negligible friction. A bookstore worker applies a constant horizontal force with magnitude 25 NN to the box. What is the magnitude of the acceleration of the box?

Answer 1

a = 0.581 m / s²

Step-by-step explanation:

For this exercise we use Newton's second law that states that force is proportional to the mass and acceleration of the body

We write a frame of reference with the x axis in the direction of the floor

F = m a

a = F / m

Let's calculate

a = 25/43

a = 0.581 m / s²

The direction of the acceleration is the same direction of the force
