A 25 kg toy car moving at 3 m/s collides elastically with a 5 kg toy car moving at -10 m/s. After the collision, the 25kg toy car is moving in the reverse direction with a velocity of -1m/s. What is the velocity of the 5kg toy car?

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up
