Still sticking to my first answer. There is no force to counter the the birds hovering. The bird is moving at 65mph with you but it's hover is not in a forward motion, it is vertical. It's position may change relative to your head, but it wouldn't slam into the front or the back window.

Now I'm more interested in a ride on the plane that can accelerate 600 mph at the flip of a coin

Couldn't you just toss up a ball while slamming on the brakes?

i would think the humming bird would remain at position X, while the car would still travel forward. if you just came to a quick stop, and the hummingbird stayed in the same spot, the rear windshield might hit it, depending on how long it took you to stop.

if the windows were down, the hummingbird would roundhouse kick you as it flew out the window, then hold up a big sign that said PWNED on it.

throwing up a ball would not work as it is not hovering at a steady position. also, tying somehthing to the car would not work as it would have an anchor that was attached to the car. We would need one of those helicopters in the car to test it properly. that way it is hovering and not attached to anything when the brakes are applied.

Click and Clack answered it (link back a few posts) and even talked to a Harvard Physicist to get his confirmation.

A car or anything that is accelerating or decelerating is what they call a non-inertial reference frame, so relative to the car, the bird's momentum- being inertial ("body in motion stays in motion") will carry it forward at the speed the car was going- the only way the bird can avoid getting smacked into the windshield is if he stops "hovering" and adjusts his flight plan so that his position decelerates with the car.

Hummingbirds are quick enough that one might be able to stay off the windshield, but not if it just hovers, and not because of a lack of force.

Acceleration is mathematically related to force, remember, f=m*a, if the car is decelerating, it has a "-a" component, and the resulting force acting on the bird is in the "+" direction and in direct proportion to the bird's mass.

Krinkov- try dropping your penny next time your plane has hit the tarmac and has the engine thrust reversed- I'll bet it hits the tray table in front of you, at the very least it will wind up under the seat in front of you and not directly below where you dropped it.

sure, give that a try...although my suggestion would be to have a passenger do the ball tossing- have them do it for a while at speed then without saying anything, hit the brakes and see where the ball lands.

This is correct. The thing to pay attention to in this example is not acceleration of the bird, but rather that of the car. Because the car decelerates while the bird has a constant speed (therefore not accelerating), the bird will indeed fly into the windshield unless it senses the change in acceleration and counters it.

That's because we were all taken to 600 mph in the plane together, air, passengers, everything...now stop the plane suddenly in mid air...where does everything go? The nosecone...because we are still moving at 600 mph, unless we were strapped to the plane, then we all travel down together...because planes aren't meant to stop.

f..k that bird, I had large black widow in my car, finally B****ch drawn in opened can of Rockstar left overnight.....BTW...what about ELEVATOR????

the bird would be dead.

someone could try to get one of those micro helicopter from frys or great mall, and take it for a drive in your car. Control the helicopter to move forward while you try to match your car's speed to the helicopter.
Stop the car suddenly, I bet the helicopter will hit the front wind shield, coz it's still moving forward at a constant velocity.

but the helicopters are hard to fly. you might hit the driver in the head haha
