I would appreciate help with c-g :)
![**Section b:**
Write your available equations (in this case the three components of the Coriolis acceleration \( \frac{du}{dt}, \frac{dv}{dt}, \frac{dw}{dt} \) and the vertical acceleration due to gravity as explained in the notes above):
\[
\frac{du}{dt} = 2 \Omega v \sin \phi - 2 \Omega w \cos \phi
\]
\[
\frac{dv}{dt} = -2 \Omega u \sin \phi
\]
\[
\frac{dw}{dt} = 2 \Omega u \cos \phi
\]
**Section c:**
Cancel out the unnecessary terms in part b—do it right there (there are no initial horizontal motions) and write down the useful equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F52b54fcd-a89c-47a3-b95a-d48387f04fd3%2F0e6fdbd4-4d7c-452b-9b3a-4756ccb7f60d%2Fkoqvrts_processed.png&w=3840&q=75)

d. **Figure out an expression for w in terms of t and g by integrating the vertical acceleration equation** (from zero to w and from zero to t).
e. **Substitute w in the Coriolis equation** (leftover in part c).
f. **Integrate your equation** (zero to u and zero to t). You should end up with an expression for u as a function of t.
g. **But what you need is the displacement x, so you need to change u in terms of x and integrate again** (zero to x and zero to t). You should end up with an expression for x as a function of t. This is not the end of the problem since you don’t have t. All you have is h.
