Answer:
Newton's second law: F=ma.
Force = mass x acceleration
This basically means, that the more massive something is, and the faster it is going, the more force the object will have.
So, the factors that can be used to find acceleration are:
F=ma
a=F/m
So, we see that the correct answer is A, mass and force.
Let me know if this helps!
