Hi, Rosie.
Can you hear mimes?

A brief of this (current from space.com) was already posted to the list (Bob V. / Ron B.) as some onlookers mouths dropped in disbelief. Personally it sounded like much fun and that there is plenty to learn from observing terminal velocitied meteoroid like objects smashing into the ground and
On the subject of
dropping objects from high places:
On
Feb. 13 a single-engine Cessna flew low over the Utah desert toward the
Bonneville Seabase at 80 knots. Pilot Patrick Wiggins checked his
altimeter.
As planned, he was just 820 feet (250 meters)
above the surface.
At
this low
Another way to make this more "intuitive" is to imagine sticking a bowling ball out the window of a car traveling 155 mph. Do you think that 14 pounds of air resistance would be on it? Imagine at over 300 mph (the 140 m/s you mentioned).

Hi
Doug,
Good
point on the density of a bowling ball. Intuitively, I would have
guessed
the
density was around 2 g/cm^3, when in fact it is barely above 1 g/cm^3
--
about
1.15 for a 16-lb ball (the mass I was assuming).
An ordinary chondrite
of
the same size would weigh close to 50
Hola Rob,
You're right about the terminal velocity of a chondrite, in the shape of a bowling ball being much faster than a conventional bowling ball. This might still be a little counter intuitive, but, here are some 9 inch diameter bowling ball terminal velocities (there's a lot of algebra
