A bumper car with a mass of 225 kg is moving with a velocity of 18.0 km/h [W] hits a bumper car of the same mass travelling with a velocity of 9.00 km/h [E]. The two cars stick together in an inelastic collision and an instant after impact move in the same direction. Calculate the final velocity of the two (stuck together) bumper cars.
