Answer:
Newton's Second Law of Motion
Explanation:
According to Newton's second law of motion, the change in velocity of a body is directly proportional to the force applied on it. Velocity is a vector quantity. It measures the magnitude of the speed as well as its direction.
F = m a
where, F is the applied force, m is the mass and a is the acceleration.
It can also be expressed as:

where, p = mv ( momentum)

Generally work done on the pitcher is mathematically given as




b)Generally K.E can be given mathematically as

Therefore

c)Generally the equation for kinetic energy is mathematically represented by


Velocity as subject



If my math is correct your answer should be 3.0 but correct me if I'm wrong
The correct answer that would best complete the given statement above is the term QUARKS. The particles that make up protons and neutrons and are thought to be basic units of matter are quarks. <span>A quark is an elementary particle and a fundamental constituent of matter. Hope this answers your question. Have a great day!</span>
