Transforming an initial condition of a solved ODE into a new

I solved a two-variable(x[t],y[t]) second-order ODE. Now I wish to transform one initial condition of the problem (x[0]) into a variable, so that I can compute the following (which I give here symbolically to convey my intention): 1) Plot[y'[tmax][x[0]],{x[0],0,100}] 2) NIntegrate[y'[tmax][x[0]],{x[0],0,100}] How can this be done? Thank you
