A possibility of extending the applicability range of nonrelativistic calculations of electronuclear response functions in the quasielasic peak region is studied. We show that adopting a particular model for determining the kinematic inputs of the nonrelativistic calculations can extend this range considerably, almost eliminating the reference frame dependence of the results. We also show that there exists one reference frame where essentially the same result can be obtained with no need of adopting the particular kinematic model. The calculation is carried out with the Argonne V18 potential and the Urbana IX three-nucleon interaction. A comparison of these improved calculations with experimental data shows a very good agreement for the quasielastic peak positions at q=500, 600, 700 MeV/c and for the peak heights at the two lower q values, while for the peak height at q=700 MeV/c, one finds differences of about 20%.
