The equation that is used to solve second law problems is F = ma. Possible Answers: Correct answer: Explanation: This question is testing your understanding of terminal velocity and Newton's second law. 6. a. the net force acting on it is greater than zero. This means that the scale is pushing up on the person with a force greater than his weight, as it must in order to accelerate him upward. This can be solved for the magnitude of the drag force of the water FDFD in terms of known quantities: The direction of FDFD has already been determined to be in the direction opposite to Fapp,Fapp, or at an angle of 5353 south of west. From the free-body diagram, we see that Fnet=Fsw,Fnet=Fsw, so we have.
