Please see the problem below. This is a question from AAMC #11. Does anyone else find this question very misleading? I immediately crossed out choice B because no where in the question does it say the object was falling from rest. One could easily imagine an instance just before an object hit the ground after it had fallen from a high place.
Which of the following statements best explains why air resistance is ignored when a compact object falls a very short distance?
A)The object's mechanical energy is constant.
B)The speed of the object remains small
C) The area presented to the air is negligible.
D) Gravity does negligible work in this situation.
CORRECT ANSWER: B) The speed of the object remains small.
