For example, problem 7.7 tells us that a body is dropped from height

*h*above the earth. We are to calculate the coriolis force as a function of time, given that it has a negligible effect on the motion, and using the velocity of a freely falling body with acceleration

**Ge**. Neglect air resistance, assume

*h*is small so that

**Ge**can be taken as constant. Then, calculate the net displacement ofthe point of impact due to the coriolis force calculated previously.

OK , so Symon proves that

**Ge(r)**=

**g(r)**-

**w x (w x r)**. (The w represents omega, the Ge represents vector g subscript e.) I guess the coriolis force is the -2m

**w x**d*

**r**/dt term. How are we supposed to solve this. Are we just supposed to KNOW what

**w**is? Nowhere in this chapter is

**w**given for earth. I would think that maybe it would be (2pi/24hrs)*

**theta^**(if theta^=theta hat=unit vector in theta direction). Unfortunately, like Symon my professor rarely works examples either. I have no clue how to go about solving this or most other problems in the book. I there a website out there that, say, gives clear, step-by-step examples for solving these type of problems? Or does anyone write a "companion book" to be read side-by-side with Symon's that actually works examples for problems like his?

Why the heck did I major in Physics?
