A truck moving with a speed of 25.4 m/s strikes a parked car. During the collision the truck and car stick together and slide to a stop together. The moving truck has a total mass of 2434 kg (including driver), and the parked car has a total mass of 1092.0 kg. The coefficient of sliding friction between the tires and the road is 0.520. How far does the truck/car combination slide? (in m)
