Question: Using a solution of dsolve/numeric in the later calculations

I have an equation for inviscid bubble expanding of the form:

ode:=R(t)*diff(R(t),t,t)+(diff(R(t),t))^2-1/R(t)=0

Sol:=dsolve(ode, numeric, initialConditions:=R(0)=R0,D(R)(0)=0)

Now, I want to plot the following expression:

Sol2:=1/R(t)

How can I do it?

 

Thanks ahead,

Mark
