Little Timmy has fallen down the well! To get him out, rescue workers lower a rope attached to a machine and Timmy ties it around his waist. The machine reels in the rope at a slow steady rate. Timmy weighs 250 N, which means gravity pulls him downward with a force of magnitude 250 N. 1. As Timmy is pulled upward at a constant speed, does the rope exert an upward force greater than, less than, or equal to 250 N? Explain your reasoning. 2. Timmy's parents get to the well frantic. They yell at the rescue workers, "Speed up this machine! We want our little Timmy up here NOW!" The machine begins pulling the rope so that Timmy's speed becomes greater and greater. Is the rope exerting an upward force greater than, less than, or equal to 250 N? Explain your reasoning. Little Timmy has fallen down the well!
