    You have a wild imagination, but I already knew that.

    Correct. What happens exactly is governed by the equations of motion. I challenged the "three musketeers" (eram, RJBeery, Lakon) to write the equations of motion , it is a better use for their time than flapping their mouths. Motor Daddy has volunteered to help them, it is going to be a blast.

    Sure, that is what makes him so entertaining. At least he's not a pretender, he doesn't know anything but he's proud of his ignorance and he flaunts it. I wonder if his family knows how stupid he is?

    Don't make me hurt your feelings. I will if I have to.

    Go ahead, "Make my day".
    Does your family know what you are posting here?

    Do you have children?

    What is the muzzle velocity of the rounds?
    What is the distance between the muzzles?
    What is the RPM of the merry-go-round?

    Yup, do you?

    Explained in post 32. Now, can you help the three musketeers find the equations of motion, D'Artagnan?
    Once you know them, you can find the answers to all the questions.
    As long as you don't know them, you are just flapping mouth.

    Do you see a problem with your response? You asked me a question and I answered it. I asked you the same question in return, and you did not answer me.

    He has? Oh well...



    Probably. Perhaps he's busy.

    1. How do you know the muzzle velocity of a round unless you first measure it?
    2. How do you know the distance between the muzzles unless you first measure it?
    3. How do you know the RPM of the merry-go-round unless you first measure it?

    I send you to measure it.

    Now answer the question, Tach, the world wants to know, do you have kids?

    Yes, I think so. That seemed to be all about proving the gun can't fire a bullet so that it moves IN A CURVE (apart, presumably from the shallow curve towards the ground that all bullets follow, due to gravity). This is about motion in a straight line. So not in conflict with what the video shows.

    What we're all saying (now that my initial error has been pointed out to me) is that the straight line in question does not pass through the centre of the merry-go-round. In fact, the motion of the figure implies the trajectory of the ball or bullet will be at an angle of around 50-60% to a line passing through the centre. (it's impossible to be more accurate without being able to stop or slow down the motion to measure it better.)

    The trajectory is not an (angled) line, it is a complicated curve.

    Um...shaking one's head means no in Western culture. I think in India it may be slightly different.
