A car of mass 1800 kg collides with a truck of mass 5200 kg, and just after the collision the car and truck slide along, stuck together, with no rotation. The car's velocity just before the collision was < 44, 0, 0 > m/s, and the truck's velocity just before the collision was < -21, 0, 20 > m/s. Use the concept of the center-of-momentum reference frame.
