1 295.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 8 900.0 kg truck moving in the same direction at 20.000 m/s. The velocity of the car ght after the collision is 18.000 m/s to the east. Before After (a) What is the velocity of the truck right after the collision? (Give your answer to five significant figures.) 4.0 x m/s east (b) What is the change in mechanical energy of the car-truck system in the collision? Your response differs from the correct answer by more than 10%. Double check your calculations. J (c) Account for this change in mechanical energy.
