At a county fair, there is a contest to see who can pull a heavy crate along the ground with the shortest piece of rope. The rope is attached to the crate at the bottom. By digging in his heels, Albert can pull on a rope with a force of 500 NEwtons. In order to budge the crate, Albert has calculated that he needs to use a force of 425 Newtons horizontally (parallel to the ground). When Albert is in his best pulling position, his hands are 95 cm above the ground.
