## Homework Statement

## The Attempt at a Solution

I've solved part (a) by solving the differential equations in the x and y directions, but for the approximation maximum range part I'm slightly confused:

1. What does it mean by "assuming the correction with k ≠ 0 is small? I tried to expand ln (1 + y) = y - y

^{2}/2 + ... to the first order but that doesn't give me a result..(unless you consider x = 0 as a result)

2. Why are there 2 maximum ranges here? The first bit is about finding the range right? Why do they call it maximum range when it is just the range at any given angle?

I know the last part involves finding the angle that gives the maximum range, which is truly the maximum range, and not as described as above..
