How fast will an object with a mass of #7 kg# accelerate if a force of #9 N# is constantly applied to it?
In this situation, we can use Newton's second law of motion, which states that force applied to an object is equal to mass times acceleration:
The given elements are the mass of the object and the force that is applied:
Now we can set our equation the way we need it:
