hi, i read in a textbook that one equation for momentum is :
where U = intial velocity, V = Final velocity
U_1 + V_1 = V_2 + U_2 ----------- (1)
Equation (1) is derieve from Equation of " conservation of momentum " and " conservation of kinetic energy". and that they assume that
V_2 is not equal is U_2 and ,
V_1 is not equal to U_1.
why did they take this assumption? ( the book did not offer further explanation)
And what does it mean physically when u take
V_2 = U_2 and ,
V_1 = U_1. ??
