Reconciling Common Sense and Newton's Laws "Timmy's fallen down the well!" To rescue a child who has fallen down a well, rescue workers fasten him to a rope, the other end of which is then reeled in by a machine. The rope pulls the child straight upward at steady speed. The child weighs 250 Newtons, which means gravity pulls him downward with 250 Newtons of force. A. (Work together) In the box at the right, draw a free body diagram of this situation that you can refer to during subsequent discussions. B. (Work individually) As the child is pulled upward at constant speed, does the rope exert an upward force greater than, less than, or equal to 250 Newtons? Explain. If you and another member of your group have competing arguments, write both of them below! C. (Work together) If you didn't do so in part B, give an intuitive ("common sense") argument that the rope exerts a force greater than 250 Newtons. D. (Work together) If you didn't do so in part B, use Newton's Second Law to determine whether the rope exerts a force greater than, less than, or equal to 250 Newtons. (Hint: The rope pulls the child with constant velocity, so what is the acceleration?)
