Answer:
The object will have an upward acceleration
Explanation:
Let's consider the forces applied on the box. We have only two forces:
- The applied force of push, , downward
- The force of gravity, , (also known as weight of the object), downward
Therefore, the net force on the box is:
Here, we know that force applied is equal or greater than the weight, so
And therefore the net force is greater than zero:
(1)
According to Newton's second law of motion, the net force on the box is equal to the product between its mass and its acceleration:
where
m is the mass of the box
a is its acceleration
Given (1), this means that
Therefore, the box will have an upward acceleration.
In this case force example we have:
So the mass of the box is
So the net force is
And the acceleration is
