"Terminal Velocity". Usually about 125 mph.
The bus, as there is a much larger moving mass.
It is due to the physical law of INERTIA! All of the objects in the vehicle are travelling at the same speed as the vehicle itself. When the vehicle is suddenly stopped by an immovable object (e.g., a concrete wall) all unattached objects in the vehicle continue to move in the direction of travel until they also encounter the immovable object or the now-stopped vehicle. Even a common housefly in a vehicle going 75 mph is also going 75 mph, and if the car hits a tree at full speed, the fly hits the windshield at the same speed as the car hitting the tree.
Yes, because average speed is all of the different speeds added together and then divided by how many speeds there are (ex: 70 mph + 60 mph = 130 mph. 130 mph divided by 2 = 65 mph (which is the average speed)) and speed is just how fast an object is moving (ex: 80 mph is the speed of something going 80 mph).

On Ford vehicles the airbags typically deploy at 25 to 30 MPH, so in a head on collision, if both vehicles are traveling at a slow 15 MPH your airbags will go off
perhaps it is bad hub bearing Tire out of balance, loose lug nuts, worn or loose wheel bearing, defect in a tire, etc.
