According to newton's 1st law, the law of inertia, if you hit a baseball with a bat it will
hurt your hand from the reaction force
accelerate according to the applied force
fly in a straight line unless an outside force changes its course
fall to the ground because of gravitational pull

The correct answer here would be : Fly in a straight line unless an outside force changes its course.

Explanation:

This principle is explained by Sir Isaac Newton´s First Law, which is the Law of Innertia. Newton was an English mathematician, philosopher, astronormer and writer, who dedicated himself to observe and study the events that happened around him to explain certain situations. One such thing, was motion, and how it affected objects. Newton lived between 1640 and 1726-27, approximately and he was the creator of some of the most important laws of physics that are even applied today. One such Law, was the Law of Innertia, or the First Law, which exactly explains that, unless changed by an outside force, an object will move forward, in a straight line, always. This is why the correct answer is the third one, in the options.
