Use the exact values you enter in previous answer(s) to make later calculation(s). A 1,295-kg car traveling initially with a speed of 25.0 m/s in an easterly direction crashes into

the rear end of a 8,500-kg truck moving in the same direction at 20.0 m/s (see figure below). 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?m/s (east) (b) How much mechanical energy is lost in the collision?
