How can I plot a second order non-linear ODE?

This is my code so far but it does not work:

syms y(t)

ode = .003*diff(y,t)== .003*9.8-3.048*10^-6*y-

9.0726*10^-5*y^2;

cond = y(0) == 0;

ySol(t) = dsolve(ode,cond)

ezplot(y(t));

I would think plotting ‘ySol(t)’ would be more interesting:

syms y(t)
ode = .003*diff(y,t)== .003*9.8-3.048*10^-6*y-9.0726*10^-5*y^2;
cond = y(0) == 0;
ySol(t) = dsolve(ode,cond)

ezplot(ySol(t));

Thanks! Would you happen to know how to scale the y and x axis?

As always, my pleasure!

Probably. What do you want to do with them?
