The ode solvers built into MATLAB are based on the runge-kutta method. Are you meant to implement your own method, or can you use ode23?

I would encourage you to read the documentation. Here is some syntax, if I read your problem correctly this should be the solution to the first part of your problem using ode23:
dxdt = @(t,x) 0.02 - 0.01*sqrt(x);
x0 = 0;
tspan = [0 600];
sol = ode23(dxdt,tspan,x0);
Also, please look at this:
doc ode23
