Most meteorites like that hit the ground with the same

On average, meteors can speed through the atmosphere at about 30,000
mph (48,280 kph) and reach temperatures of about 3,000 degrees
Fahrenheit (1,648 degrees Celsius). When meteorites do hit the ground,
their speed is roughly half what it was upon entry, and they blast out
craters 12 to 20 times their size.

It's all a function of their original size, composition, and to
some degree the entry angle. Large dense things will never
slow to terminal velocity on the way down - hit really hard.
The one in that woman's house probably started out at two or
three times the diameter.

REALLY big ones, well, they barely have time to notice there's
any air at all.

NASA is supposed to launch an asteroid interceptor in the next
week or two. The idea is to deliberately crash into the thing
at high velocity, see how much the "bump" alters the trajectory.
In theory you could do that with math/sims, but precise targeting
can be a practical difficulty in the real world. The energy
transfer can also vary according to asteroid composition. Best
to try it a few times for real. Apophis looms in our future ...
might want to detonate a small nuke near that thing - give it
a BIG bump.

Most aren't nearly big enough to reach the ground intact or
with their initial velocity. They tend to explode in the air
and then the fragments merely fall at terminal velocity like
rocks dropped off a building. That's why that lady noticed
a tiny hole in her roof and a 'rock' below.
