Sam is trying to move a dresser of mass mm and dimensions of length LL and height HH by pushing it with a horizontal force F⃗ F→ applied at a height hh above the floor. (Figure 1)The coefficient of kinetic friction between the dresser and the floor is μkμk and gg is the magnitude of the acceleration due to gravity. The ground exerts upward normal forces of magnitudes NPNP and NQNQ at the two ends of the dresser. Note that this problem is two dimensional.

- Helicobacter pylori (H. pylori) is a helically-shaped bacterium that is usually found in the stomach. It burrows through the gastric mucous lining to establish an infection in the stomach's epithelial cells (see photo). Approximately 90% of the people infected with H. pylori will never experience symptoms. Others may develop peptic ulcers and show symptoms of chronic gastritis. The method of motility of H. pylori is a prokaryotic flagellum attached to the back of the bacterium that rigidly rotates like a propeller on a ship. The flagellum is composed of proteins and is approximately 40.0 nm in diameter and can reach rotation speeds as high as 1.50 x 103 rpm. If the speed of the bacterium is 10.0 μm/s, how far has it moved in the time it takes the flagellum to rotate through an angular displacement of 5.00 * 10² rad?
