It doesn't have that perfect relationship with wind resistance.
The wind will affect it, but the wind is
not going to totally dominate its position because it has
it has enough has inertia from staying staying put and
it doesn't have perfect wind resistance. It's some of
that wind pressure will kind of go around the object.
So those are really good strategies, but they're
not gonna crack this. So let's try another if
we already know the gravity and we already and we
can measure force, those two things to be the
same. How do we know what gravity is? Oh
yeah, we have to figure out gravity first.
So assuming we knew gravity that would be the key.
Right? So we can't do this velocity experiment.
I can't think of a way unless Peter's
idea had worked. I couldn't think of a way
to do the velocity experiment, this units conversion experiment
unless we already knew the gravity. Okay, so
so think about this just a little more.

Your starting height is zero. Um they
know the V naught in terms of units per second because they
just observed what it said on the screen. So
it was 60 on the screen, they're just gonna
keep that in their pockets, right new, because that
won't be the V naught that they're going to compute
when they compute there V naught, it's not gonna
be in units for a second. They're kind of
given units for second and let's see what this V naught
is gonna turn out to be. So they fire the shot.
And at some point, I guess that maybe the
max height is the easiest point to measure at the
max height, they record what that height is,
they record how much time it took to get there.
So this is in inches, this is in
seconds, presumably the acceleration is an inches per second
per second. So everything's gonna come out so
that when I solve for V naught the only
thing that's unknown is V naught.
