29. A 1200-kg car traveling initially with a speed of 25.0 m/s in an easterly direction crashes into the rear end of a 9000-kg truck moving in the same direction at 20.0 m/s (Figure below). The velocity of the car right after the collision is 18.0 m/s to the east. What is the velocity, in m/s, of the truck right after the collision? +25.0 m/s +20.0 m/s +18,0 m/s
