Answer:

Explanation:
If we have a net force F acting on a body of mass m it will experiment an acceleration a. Newton's 2nd Law gives us the relation between these quantities: F=ma.
In our case, we want to calculate the acceleration, so we write:

With the values we have we get:

The answer is C. Potential energy
(I learned this in class recently)
I believe it is positive.
Answeill give it a go i guess
