V1 speed calculation

Is there any formulae to calculate V1 speeds ? or just use tables in AFM or software
any reference to such tables or software for B727 aircraft wud be welcome

thanks

lift coefficients is for landing, to estimate the uplift forces on the aircraft during landing ground roll..

Since the uplift force will change with speed, it would mean that the load...

B727

Is there any flight data which gives u the main gear wheel load during landing ground roll for B727 aircraft,

or any estimates for lift coefficients (Cl) , ?
