    I was really hoping he was going to convert the amount of energy needed into calories, then from calories into peanuts butter sandwiches

    If your leg has a mass of 2kg, 1.1×10^10 J of kinetic energy would require your leg to be moving at about 150 100 km/second not faster than the speed of light.

    TLDR: Their math is shit.

      Besides, if you really needed those kinds of speed, you’d obviously have to calculate with relativistic formulas. Energy is asymptotical at the speed of light.

        100 km/sec is not relativistic and even if it were, at no point would that object need to or could exceed the speed of light. Its a fundamental limit that cant be broken.

          Yeah, I was refering to the OP’s calculated result in that it’s incorrect not only by incorrect math, but also incorrect physics.

      Yeah, their answer just intuitively seems very wrong. The ratio between the kid’s weight and your foot’s weight should be equal to the ratio between their final speed and your foot’s required speed. Ridiculous.

    Not to mention the fusion reaction triggered by an FTL foot connecting with said child’s backside would annihilate both parent and child immediately.

    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.

      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?)

    Thats inefficient, you dont need to cancel the angular momentum as there was no time limit on how long it takes rhe child to enter the sun and there also was not a specified required trajectory. The child can just spiral into the sun

      Right, I wanted to ask: is that actually the minimum energy to make the child reach the sun? What’s the minimum energy to launch something so it reaches the sun?

    What if you could kick him into space, making an orbital transfer to Jupiter, from which the kid gets a gravity assist that bounces the kid into a more elliptical orbit that then sends him into the sun?

    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.
