a 3329lb car traveling initially a speeed of 40 mph CRV(estimated speed at time of impac, brakes had been applied) in an easterly direction crashes into the rear end of a 3430lbs CRV moving in the same direction at 0 mph. How far does the car hit move?

<<CRV moving in the same direction at 0 mph. How far does the car hit move? >>
How can you move and have direction at 0 mph?
You will need tire friction information to estimate how far the car(s) move. Does the rearended car have brakes applied?
