The terminal velocity of a raindrop that is 4.00 mm in diameter is approximately 8.50 m/s under controlled, windless conditions. The density of water is 1.00×103 kg/m3. Recall that the density of an object is its mass divided by its volume. If we model the air drag as being proportional to the square of the speed, Fdrag=cv2, what is the value of c?

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
