From the SUV-compact car example, suppose the same two vehicles are both traveling eastward, the compact car leading the SUV. The driver of the compact car slams on the brakes suddenly, slowing the vehicle to 6.00 m/s. If the SUV traveling at 18.0 m/s crashes into the compact car, find the speed of the system right after the collision, assuming the two vehicles become entangled, Answer: The speed of the system is ___ m/s.
