what do you do now
statement that correct
of our collections remember
we have functioned be a key
equals
the court
few months
square
so it gives us this quarter and a nickel is more after this
decreasing
bhutan gave up for decreasing at an increasing rate
when he chose calculations was their us upper estimate
we get hundred feet per second
times to set
then we did
sixty forty percent
thanks to set
and so on and so forth
what that gives us
we can represent that five
are these type things
notice that the area of interest rates of almost four hundred
times too
with its two hundred feet trap
the secretary was sixty four
times too
business travel during the second
so what we're finding is the area of these purple rectangles represents what we found
okay
no will area of all five rectangles combined uses an unprecedented
the total distance traveled
during the ten seconds
we call these left insults
the reason I called leptin sounds is because this on is created with the west and most
point
of the graph
from across gives us the right gives us the top of a rectangle
if we have left themselves
and we must have great hands and you can imagine topple be made with the right
for the record
what's her hands out
Iraq themselves
by the rectangles we made we did the well rested
we've actually read calculated
the area
of these great things
here it is first-rate table
the sixty four feet per second time since the sentence that sixty four times too
it's a different thing
it's thirty six times too
so on and so forth who
you can't see the right angle here because remember this last week high of zero
there's a fifth rectangle here
he stands on areas here
so the east
by rectangles
give us the lower estimate that at the end it was the right
so us
here they are plotting to get
we are left in some
and we also have a ready answer
now the difference between the two of the president's first estimates consider it the
second is basically this purple are here
it's and on down
now if we
add up to this purple parts
yes
how far apart are two astronauts work
one hundred times too
remember our first estimates for ATT second finals
for two hundred feet apart
okay
what about for one second
well here are upper and lower houses with three identity last year hundred feet are
in a reference to say that I recall
a day after the one second time
stimulus for always ends hundred
multiplied by whatever time interval is
so
for jews and it's two hundred feet
for once and it's a hundred feet
the with the velocity was given every of a second
well the difference between the upper and lower
what he wanted
from four hundred per ten
so we're improving accuracy
what about every hundredth of a second
we be multiplying won one hundred
by hundred in our to answers are operas would be one would are
so they'd be very accurate
now as you can imagine it the and three hundred
the second
that would be a lot of data for ten seconds that be thousand points that we have to calculate
and take lot
one of the keys would be looking at
there's this model
is the more measures we take
rosa more rectangles these
the more accurate
our estimate sir
so this case the more rectangles reason right you're going to be
what we want to thank you
the exact
distance traveled
well think it would happen if we hadn't infinitum Iraq tables
we can't kid exactly
the area between the velocity curve in the attacks
so that's going to be our goal
it's the kid
that area underneath the car in abovian taxes
as exact as possible
