Correct, a free falling object, like a coin will accelerate @ 10m/s/s till gravitational forces are equalsed by resistance forces.
The meteor is glowing hot because its burning up from friction caused by resistance to the atmosphere, the inital speed and inertia it had when it entered our atmosphere will have slowed up considerably as it looses mass to probably hundreds of miles per hour by the time it hit the kid.
