WebbIt state that both mass of objects are equal and velocity of both object should be in opposite direction. so if we take initial velocity of object A is positive and initial velocity of object B is negative. so after putting those value in formula of final velocity. We get Vaf = - Vbi and Vbf = Vai instead of Vaf = Vbi and Vbf = Vai Webbcars are deformed. The compression phase terminates when the relative velocity of cars vanishes; i.e., when cars have equal velocity (Figure 1). The compression phase (1) thus integrates the changes from initial velocities to common velocity u.
