On a snow-covered road, a car with a mass of
1.1 × 10^3 kilograms collides head-on with a van
having a mass of 2.5 × 10^3 kilograms traveling at
8.0 meters per second. as a result of the
collision, the vehicles lock together and
immediately come to rest. calculate the speed of
the car immediately before the collision.
