Two identical balls A and B having velocities of 0.5 ms^(-1) and -0.3m

1.	Two identical balls A and B having velocities of 0.5 ms^(-1) and -0.3ms^(-1) respectively collides elastically in one dimension. The velocities of B and A after the collision will be
Answer» `-0.5 MS^(-1) and 0.3 ms^(-1)` `0.5 ms^(-1) and -0.3 ms^(-1)` `-0.3 ms^(-1) and 0.5 ms^(-1)` `0.3 ms^(-1) and 0.5 ms^(-1)` Solution :Masses of the BALLS are same and collision is elastic, so their VELOCITY will be INTERCHANGED after collision `:. v_A= +u_B = -0.3 ms^(-1) and v_B = u_A = 0.5 ms^(-1)`.
