1. A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked and they stick together after the collision and are going 10 m/s after the collision. If they skid for 13.2seconds before stopping, how far did they skid? Hint: Are the aircraft moving at a constant velocity after the collision or do they experience an acceleration? 2. distance(d) = 1/2acceleration(a)*time(t)^2; 3. I am lost on this one. I am working with linear momentum equations right now but only know how to solve for the speed, not the distance.
