# hey Jill
here's the bag the stone was in when we found it

# any good at maths
ton of stone travelling forwards at @80m.p.h
drops @800ft
what's the force when it lands?
I'm very curious

# I'm crap at maths, as you well know,
but I'm sure there's somewhere online where you can put in details like that and get an answer.

# V=VO + AT^2
F = MA

I could do it, but I can't be arsed either.

Edit: In lamens:

Velocity = initial velocity + acceleration x time squared.

Force = mass x acceleration

# Potential
It's easier in potential energy....

mgh + 1/2mv^2

# need to know the mass of the stone

velocity wise it'd be 32 feet per second per second.

*edit... oh a ton! oh in that case it's...


oh damn i forgot my stoneulator

# dunno about mass but
roughly 1 cubic metre of rock wieghing 1 ton, inside a big bag
(I helped save b3ta! Dill, Wed 31 Mar 2004, 19:33, archived)
# the bag would add drag to the whole shananagan


i expect it's velocity x mass / drag + curry = explosion.

or something.

# I highly doubt it
because the mass of the stone would most likely cancel out any resistance offered up by the bag.

I mean, it would.. but it would not be very noticed.

# says mass is one ton
force = mass X acelleration

convert it all to metric and voila

# Bzzt, wrong.
The force you want to know is the force exerted by the ground to change the stone's velocity back to zero when it hits. (Actually it's the reaction to that force, but Newton's Third, right?) So there is another piece of data missing: you need to know the nature of the ground the stone lands on - if it lands on mud the force will be smaller than if it landed on an expanse of concrete, because it will take longer to come to a stop, i.e. acceleration will be lower.

# Answer
692083.5 lbs force (neglecting air resistance of falling stone; I hate fluids). People should not make grad students do data entry. They go on B3ta.

# Is that a lot then?
How many pieces would dill have been smashed into?

# In mini's
It's like setting 384.4 minis on top of dill, very carefully.

# thankee sir
considering I weigh just 64Kg and am made of soft squishy stuff, that would've smarted a bit!
