A nurse cares for a patient who has suffered a traumatic brain injury after falling from a height. The nurse knows that the severity of the injury depends on the speed at which the patient hit the ground.
Which of the following factors affects the terminal velocity of a falling object?
The shape and surface area of the object.
The mass and volume of the object.
The acceleration and momentum of the object.

Choice C is incorrect because the acceleration and momentum of the object do not affect its terminal velocity.
Choice D is incorrect because the height and distance of the fall do not affect the terminal velocity of a falling object.
