The velocity changes from a two-vehicle planar collision can be modeled by a set of six algebraic equations.The principal variables are the six initial velocity components, six final velocity components and three coefficients. The method of least squares is used to fit the model to several combinations of known and unknown variables such as those obtained from staged collisions. A combination of iteration and direct search is used to solve the estimation equations numerically.Results of calculations are shown using data from experimental collisions.
