  2. Section Business • Final is 4 hour long. • History suggests you should expect an orbit problem. • History suggests you should expect a fluid problem (continuity eq., Bernoulli’s eq., Archimedes’ princ.). • Otherwise, covers the full course, back to week 1. • I’m observing in Hawai’i Dec. 5 – 17. • only available by email: cdd@submm.caltech.edu

  3. OM, Problem 4-55

  4. OM, Problem 4-55 • Answer: maximum height = R + R/2[Rg/u2 + u2/Rg] (for u2 ≥ Rg) specific case: u = 30 km/h, R = 0.80 m, g = 9.80 m/s2 4.39 m

  5. Quiz Problem 5
