O.T: Tired Movie scenes.....

[Dark Horse]

A cliche, in fact, can have the same subtle shock effect as a deja-vu. We've seen it before, and yet... we're not sure. That is because the cinematographer understood his audience, and gave the familiar image a slight twist, almost unnoticeable. With a little imagination, the old cliche threatens to destroy our very concept of reality...

[Bill Dozer]

Oh yeah. One of the worst offenders had to be Speed (although, in that case, it was a bus full of people that was lighter-than-air, not a car).

It was booting along at 50+ mph on a bridge and - OHMYGAWD LOOK OUT!!!! - there is a large section of bridge missing up ahead! There's no ramp either! There is just flat road, then a hundred yard gap-of-doom, then more flat road at exactly the same level as the take-off point.

But they drove faster so that took care of that.

This guy argues it could actually happen. Of course he is supporting it with math covered on the day of algebra class I was out... must have been the NCAA tourney.

Roger Ebert has an entire glossary of these cliches:

I'm not buying it. I want to know what figure he used for distance.

Through the druggy haze of my past education, I remember the value of acceleration due to to gravity g = (9.8 m/s2)

They show the velocity as ~70 mph.

They gave the launch angle as 5 degrees.

That should be all the info needed. So we just need to convert g or v so the units are consistent and then plug that all into the equation . . . .


GANCHROW!!!!

[Mudcat]

Maybe I gave up too easily. I get that they are using a distance for the gap of ~17.3 meters (~19 yards). The gap looked a lot bigger than that to me.

Mind you my calculations may have gone astray.

Sounding this one out logically. (I'm assuming the angular momentum and wind resistance of the bus are both zero. I'm also treating the bus like a point mass.)

9.8 m/s² &asymp; 32.2 ft/s²
70 mph &asymp; 70 mph &times; 5,280 ft/mile &divide; 3600 sec/h &asymp; 102.7 ft/s

If the bus launches at a 5&deg; angle, then:

The bus's horizontal velocity would be 102.7 ft/s &times; cos 5&deg; &asymp; 102.3 ft/s.

And the bus's vertical velocity would be 102.7 ft/s &times; sin 5&deg; &asymp; 8.95 ft/s upwards.

So if the bus starts out going 8.95 ft/s upwards, and is then be accelerated downwards at 32.2 ft/s² by gravity, to see how long it takes the bus to reach zero height, we solve for t:
d = v₀t + ½at²
-8.95 ft/s &times; t + 0.5 &times; 32.2 ft/s² &times; t² = 0
t &asymp; 0.556 seconds

So the bus travels 0.556 seconds before returning to the same vertical height at which it left the road. Because the bus is traveling at a horizontal velocity of 102.7 ft/s, the bus is able to cover a horizontal distance of 0.556 seconds &times; 102.7 ft/s &asymp; 57.1 feet (&asymp; 19.0 yards &asymp; 17.4 meters) before returning to Earth.

Identical numbers as you, Mudcat.

[Mudcat]

Okay thank you. It's still a pretty big eye-roller of a scene in my mind but it's closer to be being plausible than I would have guessed.

I will un-hijack the thread now.

The utter artificiality of that scene was the nose of the bus lifting about 5 feet in the air upon takeoff. In reality the downward motion of the projectile would begin immediately and the nose of the bus would drop even if the vast majority of the weight is in the back of the bus.

[Dark Horse]

Combining deja-vu, or any other form of premonition, with the fact that Reeves would be 'the one', I find the bus scene entirely plausible.

[Mudcat]

And I suppose if we compare the plausibility of that bus scene, even factoring the magic wheelie to which isetcap referred, to the plausibility of Keanu Reeves being a doctor (in Something's Gotta Give.)

I am much more ready to accept the bus scene.

[Dark Horse]

Indeed. The bus scene is all taken care off.

I just hope Reeves didn't become a doctor after being the one, because that would truly boggle the mind.

Just curious where did the launch angle come from..? I would guess the wind at a high rate of speed under the bus lifted it...

I saw the movie but barely remember that scene..

In the director's cut everybody went to the back of the bus, lifting the front, then all jumped in unison, launching the bus when they came down... Elementary.

Elementary maybe but can that actually happen...?

[Dark Horse]

With 'the one' on board. Are you kidding?

[ShamsWoof10]

haha of course...

Along the same lines it always seems like no matter how fast they are going in cars, buses, planes that they should get to the target faster then they do... The directors seem to give them all the time they need but making it look like it was JUST ENOUGH...

i.e. you'll see a car heading for a cliff going 100 miles per hour but it takes it forever to get there....

Yeah I agree I don't buy the bus scene either but then again I don't buy the 9-11 scene to match... I don't think planes can really go through concrete steel reinforced walls without a lot of wreckage spattering all over on impact... Instead it gets eatin' WHOLE by a building...

[Dark Horse]

To briefly come back to the original point of walking away from an explosion without looking back.

There are two kind of explosions:
a) those created by others
b) those created by self.

To walk away from an explosion, without looking back, in the case of b) is still cool... In the case of a), however, this would be very stupid, since the force of the explosion can NOT be known. In that case the best things is to dive for cover. With the aid of this simple guideline we can determine the coolness or lack of intelligence of our hero.

Cool:

My bad ya'll I'm just f*ckin' around... I think I'm still in a drug haze and man this stuff is good... I'm so high that the wind looks like it's blowing the smoke in differant directions at the same time... Away from the plane in one and towards it in another....

I think that Stumpage, who made that point, has been upset ever since George Clooney did that in Syriana. Stumpage is annoyed how he and Clooney are always competing for the same women.

Mud,
I'm pretty sure he'll let Clooney have his first wife.

I am annoyed at that...He keeps stealin' my ladies all right, and it's no doubt because of his "too cool to look back" explosion scene.

Mind you, Clooney's was very businesslike. True, he didn't glance back at his created carnage, but then again he also didn't have the mega-cool strut going either. Just sorta all in a day's work for him, and then he was off to get a taxi or whatever.....And Cobra King is completely correct about Clooney Wife #1.....

Just wanted to take the time to thank all zero of you who helped me figure out how to put the images up...
