Question

A worker applies a constant horizontal force with magnitude 20 N to a box with mass 40 kg resting on a level floor with negligible friction. What is the acceleration of the box?

Answer 1

The acceleration of the box is 0.5 m/s²

Explanation:

The acceleration of the box can be calculated using Newton’s second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass. In mathematical terms, this is expressed as:

`a = (F)/(m)`

where:

a is the acceleration,

F is the net force, and

m is the mass of the object.

Given that the force F is 20 N and the mass m is 40 kg, we can substitute these values into the equation to find the acceleration:​

`a = (20N)/(40 kg) = 0.5 m/s^(2)`

So, the acceleration of the box is 0.5 m/s².
