A 1200 kg aircraft going 40 m/s collides with a 2500 kg aircraft that is parked and they stick together after the collision. If they skid for 124 m in 20 s before stopping, how fast were the two stuck-together aircraft going immediately after the collision? Hint: Are the aircraft moving at a constant velocity after the collision or do they experience an acceleration?
