Always funny to see the memes show up here a week after I get sent them from friends who still use Facebook and Fark.

"Then you'll be fired."
"Fine!"
"Out of a canon into the sun."
Do. It.
Why cancel the angular momentum when we can utilize it?
i may be mistaken but I don't think it can be utilized to descend toward the sun
It's the foundational principle of "Launch Windows." Because the earth rotates the sun and also spins on an axis, we can launch at a time of day that gives us time to accelerate and then leave earth orbit in the direction of earth's orbit around the sun with minimum amount of energy required. The majority of energy used is simply to escape Earth orbit. Once orbiting the sun, comparatively very little energy would be required to approach it utilizing it's own gravity.
During Perihelion the sun is 147100632 KM away, as the distance from the sun is not constant for earth's orbit.
It requires energy to shrink an orbit just as it does to grow it. Since we're launching from Earth, we start with Earth's orbit around the sun, and we have to burn enough to bring the perihelion of our launched child's solar orbit to within the sun itself. We could use Venus or Mercury for gravity assists but the angular speed of the orbit does have to be mostly cancelled to hit the sun
It's still a lot cheaper than instantaneously cancelling angular velocity.
well the other stipulation was that it has to happen from a single kick
Still this approach seems wasteful. Just making it sufficiently far from the surface travelling in the right direction should be enough... As long as you aren't in a rush.
I think I scared my wife and kid I laughed so hard.
Or just get another child. I know they don't grow on trees but I'm sure they grow somewhere
The fiery pits of hell
That not a nice name for the uterus
But still accurate. That fucker tries to kill me every few weeks for some reason.
Faster than the speed of light.
Lol that is some shit maths for a checks note astrophysics major i am shit at maths and even i know its wrong.
Are you arguing that 1.12 billion m/s is NOT faster than the speed of light, or are you arguing that the speed required by the kick is not 1.12 billion m/s? Because if it's the former, the speed of light in a vacuum is 300 million m/s (to 3 significant figures), or less than one third of that kick speed. If you're arguing the latter, I don't feel like checking all of the calculations this early in the morning, but you are probably right on that point.
Velocity addition and conservation of momentum don't work like that if the speeds are close to the speed of light.
For further details, please check out special relativity theory.
The reliable way to get an answer from the internet is to provide the wrong answer, then someone will come and correct you, providing the answer you seek. (Xkcd, probably maybe?)
This is a proven fact. Expose yourself early and often, that’s my motto.
Im not allowed within 500m of the supermarket after i exposed myself last time.
Not to mention the fusion reaction triggered by an FTL foot connecting with said child's backside would annihilate both parent and child immediately.
There would be a crater where the parent and child were, and buildings would be leveled by the resulting shockwave.
It's your own damn fault for not asking first what they wanted. Now if they DID contradict themselves I can see why that would feel that way.
Okay the math is obviously wrong, and it's not even answering the question.
The question was, how much force. If punting the kid involves a kick, let's say the foot makes contact with the kid for about 25 cm. Then the force required over this distance is on average 45 GN.
This is equivalent to the child experiencing roughly 180,000,000 G
