Nataly Lin · Answer 1

a = 0.581 m / s²

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
