The situation that exemplifies Newton’s Second Law is:
B: A baseball accelerates faster if it is thrown with more force.
Newton’s Second Law states that the acceleration of an object depends on the net force acting on it and the object's mass, typically expressed in the formula \( F = ma \), where \( F \) is the net force, \( m \) is the mass, and \( a \) is the acceleration. In option B, the relationship between the applied force and acceleration is highlighted, which is the essence of Newton's Second Law.
