  (The bowlingball will also kill you)

    A bowling ball imparted with the momentum from a slingshot won’t even have the energy to stay air-borne.

    The marble imparted with the momentum from a slingshot will fracture or even penetrate your skull.

    Momentum is m*v. However, kinetic energy is (1/2)m*v^2, where the velocity is providing exponentially more to the equation.

  What happens if you shoot them against each other with the same momentum?

    I’m not a Physicist but since they have the same momentum, the marble will have a higher velocity. Let us assume the bowling ball weighs 6000 gm and the marble weighs 20 gm (average weight), the velocity ratio of the marble to bowling ball is 300:1 (300 times faster).

    If we assume that both of them are made of the same material, and you throw the bowling ball at 1 m/s, then the marble is launched at nearly Mach 1. I’m pretty sure it will create a neat hole in the bowling ball.

    I could be very wrong as well.

    They shatter. And everyone in the vicinity dies from shrapnel.

      Would you rather get hit by bowling ball shrapnel or marble shrapnel?

        How far am I from the collision?

  This is what I assumed. Assuming its non-injurious, the marble will sting a lot more, on the other hand, I’d be under a bowling ball (or holding it.)

  If its at a significantly injurious amount of momentum, there is no right answer.
