How the hell do they get those high scores?
\_ The simulation is hideously broken. Try:
Proj. mass: 10 Counter. mass: 100 Counter. Height: 100
Launch angle: 31 Gravity: 0.815 Wind: 7
No virginia, that doesn't happen in real life.
\_ That's hilarious. Thank you.
\_ why? That's highly plausible. You shoot an object high
up with a head wind, hence the X velocity decreases while
the Y velocity goes according to gravity.

\_ Not that sharply, and I thought it was a tailwind.
\_ ever played golf? Hitting the ball with say, a sand
wedge or 9 iron, head wind, and with lots of back-spin?
That's the projectory you get. -golf player under 80 par
\_ Yeah, I've played golf, and you do know that the
physics of a light spinning golf ball are different
than a heavy slug, right?
\_ I really don't think you can change gravity and
then try to use your intuition to determine what
would happen "in the real world." -tom
\_ Physics are the same. If physics were different
for different objects it wouldn't be physics,
it would be, uhm, religion. What I think you
meant to say was that the characteristics of
a slug vs. a golf ball in an aerodynamic
environment are different, so a spinning golf
ball has a drastically different drag co-efficient
vs. a slug. Also, I believe it's "trajectory", not
"projectory".
\_ No need to do lots of math to decide this one
way or the other. Just say it's "intelligent
design" and proof that God exists.
\_ You moron. "The physics of" is a common idiom
for "the physical characteristics of", etc. Are
you really this stupid? Not only does a spinning
golf ball have a different drag coefficient, it
also has a different vector because of the
difference between the leading and receding sides
of the ball. Is this a troll? |
