Do we know how fast those small meteorites are travelling when they hit the ground? Are they like bullets or more like snowflakes?

Here’s a recent one: https://abcnews.go.com/US/scientists-confirm-meteorite-crash...
It pierced the roof but didn’t pierce the floor.
One nitpick here - meteors aren't called meteorites until they hit the surface.
for a 1m meteorite:
mass = 4/3 * pi * 0.5^3 * 8000 = 4188 kg
area = 2 * pi * 0.5^3 = 0.78 m
The defaults for density and drag coefficient are fine enough. And we get a result of at least 500m/s, assuming air resistance is sufficient to slow it down to terminal velocity. The exact number will vary quite a lot - especially as this is for a whole meter sized meteorite that doesn't disintegrate, but this is at least a reasonable ballpark. So the tl/dr would be: more like a bullet, but with somewhere around 140,000 times the kinetic energy, for a 1m meteorite.
