Consider two vehicles coming up to an intersection. One car of mass $1200$ kg is moving north with a speed of $14\frac{m}{s}.$ A truck is much more massive $(2400$ kg $)$ is slowing down from $15\frac{m}{s},$ with an instantaneous speed of $5\frac{m}{s}$ when it is $15$ meters from the intersection, heading directly west.

The car has a momentum of $16800kg\frac{m}{s}$ north

$,$ while the truck has an instantaneous momentum of $$ when $15$ meters from the intersection. When the truck has stopped at the intersection, its momentum is
