A1120 kg car traveling initially with a speed of 27.40 m/s in an easterly direction crashes into the back of a 9 490 kg truck moving in the same direction at 20.0 m/s. the velocity of the car right after the collision is 18.0 m/s to the east. (a) what is the velocity of the truck right after the collision?
