Momentum conservation often assumes that the mass of an object remains constant throughout a process or event. However, a change in momentum can also occur when mass changes. Consider an automobile with a full tank of gasoline traveling at a velocity of 88.0 km/h to the east. The mass of the car when the fuel tank is full is 1292 kg. Suppose that the car travels along a highway that extends eastward for 600 km. By the time the car has traveled this distance, it's mass is 1255 kg. What is the car's velocity at the end of the journey?
