Problem: A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked. They stick together after the collision and are going 10 m/s after the collision.
Part A: If they skid for 18.9seconds before stopping, how far did they skid?
I need expert help to solve the above question and hint: Are the aircraft moving at a constant velocity after the collision or do they experience acceleration?
