Random Rants #XXIV - The Angry Mob

[madviking]

shouldn't there be an easy formula to plug that into?

Nope.

 

[cardgame]

well that's ********.

 

[madviking]

well that's ********.

Accurate description of physics right there.

 

[Arakhor]

Actually, if the projectile was ********, you'd also need to factor in the retardation rate.

 

[spryllino]

45 degrees, I think, but then I'm no expert in Physics.

 

[W|M]

Seeing as the question is ********, I think you should say 'Twinckity-Bour!'

 

[Love]

Actually, if the projectile was ********, you'd also need to factor in the retardation rate.

Well ha, ha.

 

[Tee Kay]

Separate the vectors?

Rant: I've just woke up. I should've woken up two hours earlier.

 

[Huayna Capac357]

My head seems like it's always hurting.

And my ears are always ringing.

 

[MathNerd]

I'm too lazy to actually do the calculations, but I think you'd go about it by knowing that the velocity at half max height is given by using Pythag's Theorem on the two component vectors at half max height. Use a variable to represent the launch angle. You could use -9.8t+v0 and it's integral, -4.9t^2+v0t, to get the time at which half max height was reached. You know that the horizontal component of the velocity will stay constant, so find the vertical component of the velocity at half max height and use Pythag's to find the velocity. Set the velocity equal to 3/4 of your initial launch velocity, and solve for your launch angle (probably using sin^2+cos^2=1 along the way).

 

[SS-18 ICBM]

Aren't the unknown quantities supposed to cancel out anyway?

 

[TheLastOne36]

Yay, Chavez is in my city...

 

[really]

Yay, Chavez is in my city...

No power cuts today?

 

[TheLastOne36]

There haven't been for a while actually.

Thank you wet season for not giving Chavez an excuse to cut power.

(Although rural areas still get them, sometimes for the whole day)

 

[Joecoolyo]

Physics + WebAssign =

 

[cardgame]

hey, I bet wolfram alpha can help you with physics

 

[Tee Kay]

hey, I bet wolfram alpha can help you with physics

Only to a certain level and only if you know what you're doing.

 

[classical_hero]

Yeah, well, that's not what I meant.

You walked right into that one and now you cannot run away from it.

 

[bhsup]

It is 3:09am, I have yet to fall asleep. I've pushed back my alarm as far as I dare do so, but it's still gonna go off in less than 4 hours. Tomorrow is gonna suck.

 

[classical_hero]

I have the hiccups right now.
