I do know that if I take a bottle rocket and attach it to a Matchbox on a beltsander spinning at full speed, light the rocket, it's going to go. Unless I accidentally sand my fingertips off. 
I got my answer by cheating and reading a physics site. No, I didn't read all 15 pages!!!! Just the first and last few.
BTW, when I'm driving down the road and a fly is in the car, why doesn't the fly it the dash when I hit the brakes. And if the fly is flying around from front to back while I'm driving 55, what's the fly's speed in each direction?   |
speed relative to what?
he's basically hovering in the car since the air in the car is "not moving"
the mass of the air and his mass is so small that he can accomodate the change in speed of the car because the "air" he's hovering in doesn't all go rushing to front.
Say, like if the car's interior was 1/4 full of water. All the water would rush to the front and a fish that was hovering in the water would go with it.
