A 1 115.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 8 200.0 kg truck moving in the same direction at 20.000 m/s. The velocity of the car right after the collision is 18.000 m/s to the east.
(a) What is the velocity of the truck right after the collision? (Give your answer to five significant figures.)
