An $8000-$ kg locomotive moving with a speed of $2\mathrm{.}0\frac{m}{s}$ on straight level tracks collides with a $15,000kg$ stationary car. After the collision, the locomotive and the car couple to each other, and move together.

The total momentum of the system before the collision is closest to:

$8{10}^{3}kg*\frac{m}{s}$

$46{10}^{3}kg*\frac{m}{s}$

$0\mathrm{.}00kg*\frac{m}{s}$

$16{10}^{3}kg*\frac{m}{s}$

$23{10}^{3}kg*\frac{m}{s}$
