What People Said..
Omfg, its dangerous, think if he would missed
it...
I watched it several times and I can not tell if
it is real or fake, but it is awesome anyway!!
this is real, i saw a review on channel 5 news,
proving it was real
what made me realize this video was fake is the
fact that the stunt is too dangerous to perform

So what do you think?
Does it look like a fake and if so can you be
specific about why?
What physics concepts are important in
determining whether the stuntman makes the jump
or not?

• Could you consider
• The rate at which the stuntman accelerates down
  the slide based on the incline angle,
  gravity and friction.
• The speed at which he leaves the ramp based on
  conservation of energy.
• The time is the air based on projectile motion
  and air resistance.
• depth of pool needed based on impulse and
  conservation of momentum

What People Said..
oh come on! with that kind of speed and force,
his head would have cracked the poolor perhaps
his legs
The physics are all wrong and after watching a
few times, its pretty clear that its a hoax.
The speed of the guy down the slope is too fast
while his leaving the ramp is almost in slow
motion compared to it. The speed from the end of
the ramp wouldnt allow him to even reach the
pool and when he does, most all the water would
explode out in high showers. But we see something
akin to someone jumping in from 2 feet away.
Whoever did this wasnt a very good physicist.

Someone analyzed the projectile path..
A projectile (red) in free-fall has constant
horizontal motion (green) (not counting
air-resistance) but changing vertical motion
(blue) due to gravity. Does the Megawoosh show
this?

Heres the data..
This is a video analysis of the vertical motion
for the flight with a quadratic fit
7
Heres the data..
This is a video analysis of the horizontal motion
for the flight with a linear fit

So is it possible to do this stunt?
