text: a bus is traveling at 100kmh-1.? a terrorist ,who sit at the front,shoot a passenger at the back of the bus.the bullet also travels at 100kmh-1.people outside the bus will see the bullet is not moving right? wrong!  the people outside the bus will see the bullet falling, assuming the bus is long enough to allow someone to notice such an event.  but theoretically you are correct.  let me ask you a question:  what makes you think of such things?
