Modified Euler's Method (or RK2)

I wondered if someone could do this for me so that i can use it as an example to learn from, it is from a past paper for an exam i will be sitting soon.

Suppose that a sky diver steps out of an aeroplane at an altitude of 10,000ft and that his downward acceleration is given by:

dv/dt = 32 - 0.005v^2

Use the modified Euler Method's with step size (h) of 0.5s to approximate the speed after 2s.

I vaguely understand it but exactly how to do it evades me.

Any help would be appreciated! :smile:

We help you do your homework. We do not do your homework for you. This means you need to show some work before anyone here will help you out.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
