\[M_{car1} V_{car1(initially)} + M_{car2} V_{car2(initially)} = M_{car1} V_{car1(final)} + M_{car2} V_{car2(final)}\] Since they collide with each other...their velocities are the same at the end so \[M_{car1} V_{car1(initially)} + M_{car2} V_{car2(initially)} = (M_{car1}+ M_{car2}) V_{cars (final)}\] You have Mcar1, Vcar1, Mcar2, Vcar2....so rearrange and solve for V_final

no they don't have the same velocities at the end
