Final answer:
The hummingbird, with the lowest mass of 3g among the options, would require the least force to accelerate, according to Newton's 2nd Law of Motion, F=ma.
Step-by-step explanation:
According to Newton's 2nd Law of Motion, which states that the force required to accelerate an object is equal to the mass of the object multiplied by the acceleration (F = ma), the bird that would require the least amount of force to accelerate through the air is the one with the least mass. Therefore, comparing the masses of the given birds, the hummingbird with a mass of 3g would require the least force to accelerate.
